 "prompt": "An ultra-clean 3D geometric portrait of the man in the reference image, maintaining his exact facial identity and proportions. The entire bust is constructed from discrete 3D primitives: cubes, spheres, pyramids, and cylinders. The hair is a sculptural cluster of red spheres and cubes; the beard is composed of sharp, interlocking red triangular and polygonal shards. The face is a faceted white geometric assembly with high-contrastred accents. Color palette: strictly Red and White only. Lighting: soft studio lighting with subtle ambient occlusion to define edges. Background: pure solid white. Style: abstract 3D sculpture, octane render, 8K, high-end digital art aesthetic, 16:9 aspect ratio.",
