[fluid marbling] stretches across a 3:2 frame as the main subject, occupying almost the entire image with sweeping veins and folds that fill the center and extend to all edges to preserve the target crop and composition. [dark charcoal base] forms the dominant background tone that covers roughly 70% of the plane while [metallic gold accents] trace veins and scattered splatters concentrated toward the upper-right and along sinuous ribbons. The viewpoint is straight-on and medium-wide so the swirls read as large, continuous shapes rather than distant details. Lighting is soft but directional, producing gentle highlights, glossy reflections along curved surfaces and deep, short falloff shadows for contrast. Surface detail shows smooth, liquid-like reflections with subtle particulate specks in the gold, and a polished sheen across darker areas. Render as a photoreal 3D-style abstract scene with crisp edges, shallow micro-roughness on metallic areas, and a balanced dark-to-warm color bias to match the reference image.
