    "prompt": "Move this exact same musician, still seated on the same wooden chair and playing the same cello, from the practice room to the middle of a vast frozen lake at blue hour. Keep his face, curly black hair, round tortoiseshell glasses, closed eyes, moss-green cable-knit sweater with rolled sleeves, charcoal trousers, brown boots, bow position and the honey-brown cello with its worn varnish identical. The new setting: smooth dark ice with white cracks and a light dusting of snow around the chair, snow-covered pine forest and mountains on the far shore, a deep blue twilight sky with a thin pink glow on the horizon and the first stars. A small warm light from a lantern on the ice beside the chair lights his face and the cello, while the rest of the scene is cool blue. His breath is faintly visible in the cold air. Remove the practice room completely.",
