赛璐珞插画：自信而强烈的表情

Create a high-contrast open-world crime game-style vector / cell-shaded portrait illustration.
Hard cell-shading only. No gradients. No soft rendering. No painterly effects.

COMPOSITION & FRAMING (STRICT):
Medium close-up (head, shoulders, upper chest visible)
4:5 vertical aspect ratio
Subject perfectly centered
Shoulders fully visible and balanced
Top of hair slightly cropped
Subject fills 75–80% of frame

POSE & EXPRESSION (LOCKED):
Front-facing
Direct eye contact
Confident, intense expression (subtle, natural — not exaggerated)
Slight tightening around eyes and jaw for intensity
No head tilt or dynamic angle

LIGHTING (CRITICAL):
Strong directional light from top-left
Left side brightly lit
Right side in deep shadow
Sharp shadows under eyebrows, nose, cheekbones, jawline, and neck
High contrast with clear separation
No flat lighting

STYLE EXECUTION:
Use 3–5 distinct tone blocks per area
Angular shadow shapes (no smooth blending)
Bold, clean outer outline around entire subject (clearly separating subject from background)
Fine inner lines for details (skin folds, wrinkles, hair strands)

FACIAL DETAIL:
Preserve natural skin texture
Include subtle under-eye folds and light forehead lines
Maintain natural asymmetry (avoid perfect smoothing)

HAIR:
Match exactly as in reference image
Preserve natural hairstyle, density, hairline, and texture
Do not add volume or stylize beyond reference

FACIAL HAIR:
Match exactly as in reference image
If clean-shaven → keep clean
If stubble → subtle texture
If full beard → detailed, dense texture
Do not add or exaggerate facial hair

CLOTHING:
Simple black crew-neck t-shirt
Visible folds and shading (not flat black)

BACKGROUND:
Clean white background
Behind head: bold mustard-yellow rough brushstroke
Irregular edges, slightly diagonal for contrast

OUTPUT:
Ultra sharp edges
Crisp vector finish
High contrast
No blur, no softness
No missing outline
