How to use six blending modes for effective shading
04. Light & Shadow Formula
Concepts of form and drawing: overlapping and foreshortening
Visualizing shapes and sightlines
The rule: invisible planes become shadows
Viewing direction equals lighting direction
05. Highlight Placement FormulaWhy do highlights appear?Surfaces where highlights form: incidence, reflection, and normalsExpanding highlight areas
06. [Student Work Review] Logical Shadow CalculationIdentify awkward areas in full- or half-body illustrationsSimplify into shapes and rebuild formsRecalculate and reconfigure shadow locations
07. Bonus: Simplified Human Figure Drawing 01
08. Bonus: Simplified Human Figure Drawing 02Selections from the first series of Rinotuna’s lectures to aid smooth learning
10. [Student Feedback] Direct Sunlight Shading Error 01: FaceStructural differences in male vs. female facesShading by style: deformation and difference
11. [Student Feedback] Error 02: Upper Body & Shoulder StructureWhat to focus on: structure or form?Female upper body: structure-centric shadingMale upper body: form-centric shadingAligning vision and structure
12. [Student Feedback] Error 03: Lower Body & Pelvis StructureSilhouette vs. structure conflictsStarting from inner pelvis, not outlineUnderstanding thigh cross-sections (think tear-drop shape)Hip rendering: mound and cavity structuresChoosing expression style and tools
13. Reflected Light & Occlusion ShadowWhy subtle tones inside shadows matterRoles of primary light, reflected light, ambient light, and occlusionLayering light/shadow by hierarchyThree-checkpoint light and shadow checklist
14. [Student Feedback] Clothing Folds Analysis 01: PrinciplesWhy study clothing folds structurally?Three elements: contact point, empty space, force directionFolds develop in empty spaceDirection of force dictates fold flowThe 3 structural properties of folds
15. [Student Feedback] Clothing Folds Analysis 02Folds are for understanding, not copyingExplore a taxonomy of nine types of folds
16. From Simple to Complex Structure ModelingShift from ‘drawing structure’ to ‘building structure’Three-stage structure modeling: size, depth, sharpnessStep-by-step modeling routineExamples by clothing fit: overlaying structure on basic shapesExpanding drawing into 3D shaping

18. [Student Feedback] Tone DistributionWhy aren’t planes uniformly shaded?Lambert cosine curve theoryWhy evenly divided tones feel flatDesigning tone distribution by structure
19. Coloring Stage GuideSketch: structural planning from doodlesShadow layout: two-tone plan based on structureColor and brightness: light direction & tone compressionTone detail: refine structure and surface materialsFinal: adjust overall tonal balance
20. [Student Feedback] Style-Based Shading ApplicationCasual, realistic, cel-shaded style approachesWhat is tone deformation?Comparing shading by styleGuidelines: what to preserve and what to adaptStyle variation case studies
21. Practice Project 01: Male CharacterStrong bodily muscular structureRich contrast in tone
22. Practice Project 02: Female CharacterSoft anatomy with crisp clothing fold sharpness

Outro
23. Easy-to-Miss CheckpointsIs the form simplified yet consistent?Do forms look like spatial structures?Is the structure rich and properly shaped?Is the tone applied appropriately per structure?Is this based on habit or thoughtful design?
24. Final MessageHow to apply what you learned to your artExpanding your studies furtherWhat kind of drawing would you like to create next?
