Prompt
Render a photoreal 3D scene in a 2:3 portrait ratio showing one humanoid robot seated at an old upright piano in a ruined urban street. The piano occupies the center-left lower third of the frame and the robot sits center-right lower third on a simple wooden stool, hands on the keys and head tilted slightly forward, filling roughly one quarter of the frame vertically. The background contains five damaged multi-storey concrete buildings that fill the upper two-thirds of the composition with broken windows and exposed rebar, and generous negative space in the foggy sky above. The foreground is strewn with rubble and scattered bricks across the bottom third with uneven piles leading toward the piano and robot. Light is soft, cool and diffuse with muted backfill that sculpts the robot's metal plates and creates gentle rim highlights along the shoulders and knuckles. Materials: weathered oxidized metal on the robot with seams, rivets and matte panels, cracked varnish and dust on the piano, rough concrete and brick textures on buildings and debris. Focus is moderate with the robot and piano rendered crisp while background towers recede into soft atmospheric haze to convey depth.
