📝 Description

This is KETO’s 5th Coloso class and the final installment of the series — a deliberate step-by-step record of how a professional freelance concept artist actually finishes illustrations, not edited speed-paints. The core message from the Class Intro: “Take the final step toward becoming a professional illustrator. Refine your lighting, color, and visual storytelling skills through KETO’s complete illustration workflow.”

Part 01 is a vertical female illustration (Vetti): purpose planning for verticals trending on social media, project brief and roadmap, thumbnail sketching, dynamic compositions, value sketches for mood and lighting, color roughs that preserve values, form refinement for efficient line art, dimensional outlines and internal details, masking and line-art color adjustment, then first-pass detailing (face and skin where the eye lands first, hair highlights, clothing materials, sparkling accessories, background depth) followed by mid-process eye-flow adjustments and a richer second pass (luminous skin, loose hair strands, material textures with brushes, transparent props, effects) closed with post-processing balance and direct-viewer interaction.

Part 02 is a vertical male illustration (Demon King) built from color thumbnails: combining color roughs and value sketches, shape blocking to preview the final, large-to-small form refinement, rough-stage post-processing to lock the final direction, sketching beyond blocking, drawing checks with lighting direction and grid depth, drawing-plus-color-rough form fusion, refined outlines and internal line art, masking, then low-light skin, grid-built bodies, deep hands, hair texture, horn surface, fur-cape volume with patterned dimensionality, soft reflective fabrics and folds, cape accessories, imp / tail supporting elements with shallow-depth background, Mixer Brush surface texture, silk textures, layered effects and final post-processing.

Part 03 scales the same workflow to horizontal multi-character illustration: purpose analysis for horizontals, matching proportions in one composition, detailed main / sub-character / background sketches, value-to-color-rough conversion, sub-character and background rough refinement, environment setup, main-character outlines and props, sub-character outlines and background line art, internal line art for main character and monsters, masking, main-character skin and hair rendering, body / prop / Trash Monster / Vetti / Medusa material passes, background depth and perspective, eye-guiding mid-process adjustments, second-pass face / hair / body / weapons / Jelly Broom / translucent liquid / background separation, train-detail balancing, post-processed presentation and focus-driven final check.

Class Perks close the loop for practice: unlimited access to 70 chapters, full A-to-Z workflow, original .psd practice files and 64 .abr brushes, .pdf guides and KETO Auto Action Set, plus About Freelancing and Outsourced Projects (.pdf). Total: 70 videos, level Advanced~Pro. Card built from the manufacturer page via browser-rendered dump (template B/catalog-curriculum, HTML 1112911 bytes, 4/70).
