窄廊尽头，洋红补光切开半张脸

A cinematic digital painting: a tight, intimate 9:16 head-and-shoulders portrait of a lone character in a narrow, dim corridor, set slightly off-centre so the figure feels poised and still yet dynamically balanced. The palette leans cool blue with magenta accents that echo #1E3A8A and #7C3AED. A cool blue wash covers walls and floor, a faint shimmer of breath hangs in the haze, and a strong magenta fill grazes one side of the face, making the eyes glow intensely and splitting skin and hair into a dramatic two-tone. Cool plaster walls show subtle grain, a matte fabric collar feels tactile, and faint metallic hardware runs along the corridor edge as quiet detail. Keep every surface clean and unlettered; micro-markings are only abstract lines and scuffs on the floor hinting at age and use. Depth is shallow: the nearest facial features resolve crisply while the corridor falls away into soft atmospheric blur, giving layered depth and gentle plane separation, with light sculpting the contours softly. One small prop, a worn keycard clipped to a pocket, supplies a narrative cue without crowding the frame. Painterly brushstrokes run throughout, with the finest detail saved for the eyes and skin.
