Prompt
Render the subject as carved marble with coherent sculptural planes, subtle stone translucency and restrained veining, with chisel and rasp marks visible in the stone. A single adult human skull carved from pale marble, seen in three-quarter view with the jaw attached, the cranial sutures, eye sockets, nasal opening, cheekbones and teeth carefully accurate, resting on a plain stone plinth.
Light: soft north-window light from the upper left in a quiet gallery, a gentle gradient across the dome and deep soft shadow in the orbits, a warm translucent glow at the thin edges of the bone and a faint reflection on the plinth, with a dark grey-green wall behind for contrast. Palette of ivory marble with grey veining against deep slate; calm, sculptural, polished.
Wide 16:9 landscape frame. No people, flesh, blood, readable text, labels, numbers or logos.
