Scultura Assemblata in Pietra Frammentata

  "task": "image_to_image_style_transfer",
  "input_image": "the reference photo",
  "prompt": "A 3D studio composition recreating the main subject from the reference photo as a fragmented stone assemblage. The subject is composed of separate, clearly detached rock pieces with small visible gaps between shards and no merged geometry. Material: fragmented [slate and sandstone] shards with chiseled edges, crisp fractures, visible stone grain, fine micro-scratches, and realistic tactile roughness. Color palette: predominantly dark slate with subtle warm-ochre sandstone accents. Lighting: soft studio key light from top-left, gentle fill light, subtle contact shadows beneath each shard, realistic ambient occlusion in crevices, and minimal clean reflections. Background: minimal off-white seamless backdrop, smooth and untextured. Framing: centered, straight-on eye-level medium shot, with the subject completely recognizable. Scattered tiny stone chips rest near the base for depth. Preserves the exact silhouette, identity, and proportions from the reference photo.",
