Illustrator Essential Training vs Visual Elements of User Interface Design

Tony Harmer walks through Illustrator's core in a logical sequence — artboards, selection, shapes and line tools, path drawing and transformation, color models, gradients, strokes, brushes, layers and groups, patterns, appearances, transparency, type, image placement and export — and the 2024/2025 editions add a section on generative AI content. Across five released versions the official rating sits at 4.8/5 (2024: 1,148 ratings; 2021: 1,914; 2022: 1,676; 2023: 1,320), an unusually high and stable signal. Reviewers describe the material as dense and thorough; the main critique is that some assignment toolbars don't match the learner's default setup, and that experienced users hit familiar ground before the advanced sections.

Tony Harmer — a certified Adobe Creative Suite Master with 40+ years in the creative industry and close ties to the Illustrator product team — is the standout asset. Reviewers repeatedly single out his delivery as "detailed, easy to follow, and even entertaining," and even a 17-year Illustrator veteran reported learning new tricks. His voice, pacing and articulation draw consistent praise. The only recurring instructor complaint is occasional mismatch between his on-screen toolbars and a fresh install, which can briefly confuse beginners.

LinkedIn Learning is $39.99/month or roughly $19.99/month billed annually, and the course is also bundled with LinkedIn Premium Career and free through many public-library cards. For learners who already hold a LinkedIn subscription or library access, this 5–7 hour course is excellent value and the completion certificate posts straight to a LinkedIn profile. Paying the standalone monthly fee for this one course is less compelling — independent reviewers call the subscription "more on the expensive side" and "expensive if used infrequently," and the certificate is not accredited. The equation flips for prolific learners who tap the 20,000+ course catalogue.

Each lesson ships with downloadable exercise files and the course includes 22 quizzes for self-assessment, so learners practice alongside the instructor rather than just watching. The gap, flagged by multiple reviewers, is open-ended project work: the exercises are instructor-led replications rather than briefs that push learners to design their own piece, and one reviewer asked directly for "more practice sessions or more question examples." There is no portfolio-grade capstone and no instructor feedback on submitted work.

The skills taught — vector paths, transformations, color, type, brushes, patterns and export for print and web — are genuinely foundational and transfer directly to real Illustrator work. Reviewers describe the tool demonstrations as practical and immediately usable, and a decade-lapsed user called it a strong refresher on newer tools like the curvature tool. The certificate carries professional signalling value on LinkedIn but is not an accredited credential, so it complements rather than replaces demonstrated portfolio work.

The course is the first of two CalArts UI courses inside the broader UI/UX Design Specialization and is structured across five modules completed in roughly two weeks at ten hours per week. It deliberately stays in the "visual" lane: what an interface is, the designer's role, and how meaning is constructed through colour, typography, imagery, grids, and layout hierarchy. Rather than tooling tutorials, it teaches a vocabulary — the formal elements that make an interface read as clear, consistent, and intuitive — through lectures and short visual exercises that culminate in a peer-reviewed final project. Learners repeatedly describe the content as a strong, well-sequenced introduction. Reviewers note that each week builds toward the final project, and that the colour and typography material gives beginners a shared language they previously lacked. One four-star reviewer summarised the consensus: "Contents covered were relevant and instructors explained all the details very well." For someone with no formal design background, the curriculum does exactly what it sets out to do. The recurring and well-evidenced criticism is depth. A meaningful share of three- and four-star reviews describe the material as "way too basic," and practising designers consistently report that the course offers little to upgrade an existing skill set. Several reviewers also flag that it does not teach the Adobe Creative Suite tools (Illustrator in particular) that the final project assumes, so learners can find themselves needing software skills the course never delivers.

The instructor is Michael Worthington, a faculty member in the Program in Graphic Design at CalArts and a co-founder of the Los Angeles design studio Counterspace. His teaching is one of the most reliably praised elements of the course. In an independent walkthrough of the full specialisation, designer Romy von Erlea wrote that the course "focuses on the principles of UI design. It is very instructive, and the explanations are easy to follow," and that Worthington "covers all the basics in a beginner-friendly way, so even the most unprepared of the students will be able to follow up." Reviewers value the clarity and pacing of his lectures, with several noting that the teaching methods and videos were "so insightful" and "covered everything necessary" for a foundation. The grounding in graphic-design fundamentals — rather than the latest UI tooling trend — gives the instruction a durability that purely software-led courses lack. The most pointed criticism of the teaching is aesthetic rather than pedagogical: a small number of one-star reviewers felt the visual examples were dated, with one writing that the course teaches "very strange visual design. Straight out of [the] 90s." This is a minority view, but it recurs often enough to note for learners who expect a contemporary, product-design-led aesthetic.

The course can be fully audited for free, which gives access to all video lectures and exercises. Multiple reviewers — and both independent blog authors who completed the specialisation — cite the free-audit option as the single biggest reason they chose it; Romy von Erlea wrote that "what drew me to this one in particular was that I could do it free of charge." To submit the peer-graded final project and earn a certificate, learners need a Coursera subscription (Coursera Plus is roughly $59/month) or to purchase the specialisation. For beginners, the value proposition is strong: a CalArts-branded visual foundation at zero cost to audit, with a low time commitment. One reviewer noted the course "was fun and easy to get through! Not demanding of my time at all," which makes it an efficient on-ramp before committing to the rest of the specialisation. The value caveat is audience-dependent. Practising designers who pay for the certificate may feel the content does not justify the cost relative to what they already know, and Coursera's subscription billing has drawn general consumer complaints independent of any single course. For learners who only need the visual foundations, auditing for free is essentially unlimited value.

The course is project-anchored: each module builds toward a final design project that learners submit and that is then peer-graded by other students. The project itself is well regarded — reviewers like that the structure "builds up to the final project" and that the early coursework feeding into it was "actually incredibly helpful." As an applied exercise, it does push learners to translate the colour, type, and layout concepts into a concrete artefact rather than absorbing them passively. The friction is the grading mechanism, which is the most contentious aspect of the entire course. Because design quality is subjective and the graders are fellow learners — many of them beginners — reviewers repeatedly report that scores feel arbitrary. One three-star reviewer wrote that "the peer grading system in an abstract field like design is not suited," and a four-star reviewer who praised the content added that "the peer-scoring doesn't work really good though." A further practical gap: the final project leans on Adobe tools the course does not teach. Reviewers advise learning "how to use Illustrator a bit beforehand," and one one-star reviewer complained that the course doesn't "teach one thing on how to use any of the programs in [the] Adobe creative suite." The project is pedagogically sound but its execution depends on external software skills and a peer-grading lottery.

The course teaches transferable visual literacy — colour relationships, typographic hierarchy, imagery, and grid-based layout — that underpins essentially all interface and graphic design work. Reviewers describe it as a genuine foundation rather than a novelty: "a very strong introduction to the concepts and the foundation for understanding UI/UX," in the words of one five-star learner. For someone with zero design background entering a UI/UX career path, that vocabulary is directly applicable to subsequent study and junior-level work. Reddit discussions of the parent specialisation echo this, framing the CalArts courses as an accessible, affordable entry point for UX/UI career transitions, with commenters noting the field is "insanely in-demand right now." The course's principles also carry into adjacent disciplines — graphic design, web design, and presentation design — because it teaches formal visual reasoning rather than a single product workflow. The applicability ceiling is real for experienced practitioners. Several reviewers from a design background concluded it would be "unsuitable if you want to upgrade your skills," and others wanted more depth and modern, product-centred patterns. The course transfers well to real work for beginners building from nothing; it transfers poorly as continuing education for those already working in design.
