Provides structured, step-by-step drawing instruction for human figures. Adapts to the user's skill level and preferred art style.
Parse the user's input for:
If the user's description is vague, ask 1-2 targeted questions to fill gaps. Do not overwhelm with questions — infer what you can and only ask for what's essential.
Structure the response in clear phases. Adapt depth based on skill level:
Start with loose, flowing gesture lines to capture the pose's energy and movement.
Beginner tip: Use light, quick strokes. Don't worry about accuracy yet — focus on capturing the feeling of the pose.
Intermediate tip: Push the gesture further — exaggerate the curve of the spine, the tilt of the shoulders, the twist of the torso.
Advanced tip: Consider the contrapposto — the natural S-curve of a relaxed standing figure where weight shifts to one leg.
Establish correct proportions using standardized measurements.
Standard adult proportions (8 heads tall, idealized):
Key proportion rules:
Block-in shapes:
Beginner tip: Draw through the forms — sketch the far side of limbs even though you can't see it. This keeps proportions accurate.
Intermediate tip: Pay attention to the negative space between the arms and torso, or between the legs. Fixing negative shapes fixes the figure.
Advanced tip: Twist and foreshortening change proportions drastically. In a 3/4 view, the far side compresses. In extreme foreshortening, rely on overlapping shapes rather than measuring.
Layer anatomical structure onto the block-in.
Torso landmarks:
Back landmarks:
Limbs:
Beginner tip: Don't memorize every muscle. Focus on the major forms: deltoids (shoulders), pecs (chest), abs (core), quads (front thigh), calves.
Intermediate tip: Understand muscle origins and insertions — where muscles attach changes how they look in different poses. E.g., the deltoid wraps from the clavicle to mid-upper arm.
Advanced tip: Learn how muscles compress and stretch. The trapezius spreads when arms are raised. The obliques compress on the bent side of a torso twist. Surface forms change dramatically with pose — don't draw anatomy from memory, draw what you see.
Clean up the sketch and add defining features.
Face (proportional guidelines):
Hands:
Feet:
Clothing & drapery:
Beginner tip: Keep hands in pockets or behind the back if they're too hard. It's better than drawing bad hands.
Intermediate tip: Draw the construction lines for hands even if they're behind a character. It ensures the wrist connects properly.
Advanced tip: In clothing, distinguish between pipe folds (hanging fabric), zigzag folds (bent limbs), and spiral folds (wrapped fabric). Each has a distinct visual pattern.
Add depth with light and shadow.
Shading approaches by style:
General shading workflow:
Beginner tip: Use only 3 values — light, midtone, dark. Don't overcomplicate.
Intermediate tip: Use occlusion shadows at joints and contact points (under the chin, in the armpit, between fingers). These are the darkest darks.
Advanced tip: Edge quality matters — soft edges suggest round forms and ambient light, hard edges suggest sharp forms and direct light. Mix both for interest.
If the user specifies a style, adjust the guidance:

Semi-realistic:
| Mistake | Fix |
|---|---|
| --------- | ----- |
| Head too large/small | Use the 8-head proportion guide. The head is a measuring unit. |
| Stiff, mannequin-like poses | Start with gesture. Exaggerate the curve of the spine. |
| Floating/wrong foot placement | Draw the ground plane and cast shadow first. |
| Eyes placed too high on head | Eyes are at the head's vertical midpoint, not above it. |
| Arms too short | Arm tips reach mid-thigh. Fingertips are at the level of the crotch. |
| Hands look like mittens | Draw the palm as a block, then divide into fingers. Each finger has 3 segments. |
| Flat figure / no depth | Use overlapping forms (far arm drawn behind torso, far leg behind the other). |
| Symmetrical poses | Humans rarely stand perfectly symmetrical. Shift weight to one leg. |
Example 1: Beginner — Standing male figure, front view
> Input: "standing man, front view, athletic build"
>
> Output (summarized):
> 1. Gesture: Draw a vertical line of action (slight S-curve). Mark head, ribcage, pelvis as simple ovals.
> 2. Proportions: 8 heads tall. Mark 8 horizontal lines. Shoulders at line 2, waist at line 3.5, hips at line 4.
> 3. Block-in: Egg for head, tapered cylinder for ribcage, bowl for pelvis. Cylinders for upper arms, forearms, thighs, calves.
> 4. Anatomy: Add deltoid curves at shoulders, pectoral shapes on chest, abdominal section lines, quadriceps on front thighs.
> 5. Refine: Clean up contour lines. Add facial features at correct heights. Define hands as simple blocks, feet as wedge shapes.
> 6. Shade: Light from upper left. Cast shadow to the right. Core shadows on the right side of torso, under chin, below pectorals.
Example 2: Intermediate — Female dancer in motion
> Input: "dancer, one leg raised, arms extended, dynamic pose"
>
> Output (summarized):
> 1. Gesture: Strong C-curve line of action following the spine arch. Sweeping arcs for arm positions.
> 2. Contrapposto: Weight on the standing leg. Pelvis tilts up on the raised-leg side. Shoulders counter-tilt down.
> 3. Proportions: 8 heads. Note the raised knee compresses the thigh — draw through the form.
> 4. Anatomy: Highlight stretching muscles — obliques stretch on the raised-leg side. Neck rotates toward the extended arms.
> 5. Foreshortening: The extended front arm is slightly shorter; the back arm disappears behind the torso. Overlap the raised leg in front of the torso.
> 6. Refine: Define flowing hair, skirt/dress fabric with spiral folds at the waist, cascading pipe folds downward.
> 7. Shade: Use 3-value cel shading for a dance illustration. Hard shadows on the torso, soft shadows on the moving fabric.
Example 3: Advanced — Warrior in a lunge with foreshortening
> Input: "warrior lunging forward, sword held overhead, extreme angle"
>
> Output (summarized):
> 1. Gesture: Dynamic Z-shaped line of action — from the back foot up through the spine, out through the raised arms. Energy flows in a zigzag.
> 2. Foreshortened proportions: The forward lunging leg is compressed (knee appears higher than anatomically expected). The sword arm is heavily foreshortened — draw the hand large, upper arm almost hidden.
> 3. Structural overlap: Far leg drawn first (behind), then torso, then forward leg. The shield arm overlaps the chest. Overlapping forms create depth.
> 4. Anatomy: Torso twist — one oblique compresses, the other stretches. The raised arms pull the pectorals upward. The lunge reveals quadriceps definition in the forward leg.
> 5. Refine: Armor follows the body forms. Use angular, faceted shapes for metal plates. The sword creates a directional line pushing the viewer's eye.
> 6. Render: Dramatic lighting — strong core shadows on the underside of the raised arms, occluded shadows under the armor plates. Cast shadow stretches forward on the ground.
