Modular Wooden Block Relief Portrait

General "Modular Block Embossing System" prompt (Identity Lock – Rigorous)
Use the uploaded image as the subject and sole identity reference.

Identity lockdown – strict (non-negotiable)
Preserves precise facial structure, proportions, and feature positioning. Do not change the eyes, nose, mouth, or contour. Maintain expression and recognition.

Posture and composition – locking
Preserve original angles, composition, and perspective. Rotating, mirroring, or changing camera angles is prohibited.

Style Shift – Wooden Block Relief (Hardcore)
Transform the entire image into densely arranged woodcarved structures:
Using interlocking wooden blocks, sticks, and carved slices, all shapes (face, hair, clothing, background) are reconstructed.
A mix of rectangular wooden beams, round columns, cross-sectional slices, and stacked planks is used.
Maintains extremely high fill density with minimal gaps (no empty flat area).

Material Systems – Wood (Critical)
All elements must be real wood, with clear grain, rings, and natural variations.
The wood grain direction must follow the shape of each component (random grain is strictly prohibited).
Includes cut endfaces, wood joints, and minor defects.
Finished product: matte to semi-matte natural wood (no plastic feel, no shine).

Depth and structure – hard relief
Build multi-layer deep stacking (foreground, midfield, background wood blocks).
Components must overlap, interlock, and be staggered in depth like carved walls. Use deep transitions rather than smooth shadows to preserve facial topology.

Facial and Hair Integration – Unified System (Critical)
The face and hair must be constructed from the same wooden block system. The hair is expressed as elongated sculpted segments extending along the natural direction. Facial features are defined by precisely placed miniature wooden blocks and contours. Materials are not separated—made entirely of wood.

Illumination – Forms are presented
Use directional lighting to emphasize depth, edges, and texture. Shadows must be reinforced with layered separation and structural clarity.

Negative prompt (strict)
Strictly avoid smoothing skin, no paint coverage, and no smoothing shadows. Metal, plastic, or non-wooden materials are strictly prohibited. Loose abstract shapes or soft mixes are strictly prohibited. Distortion of facial structure or perspective is strictly prohibited. Cracks or blank areas are strictly prohibited — maintain a dense structure.
