原始提示词
MAIN SUBJECT (IDENTITY) Use the person from the reference photo as the main subject. Keep their exact facial features, hairstyle, skin tone, and expression perfectly unchanged preserve all realism, emotional depth, and subtle facial lighting. Allow changes only in camera position, background motion, and atmosphere. A minimalist side-profile portrait of a new person, framed from the chest up and positioned in strict profile against a textured dark concrete wall (approx. #282F32). The pose remains relaxed and composed, with the subject facing left, eyes gently closed or lowered, maintaining a calm, introspective expression. Style the subject in monochromatic, winter-inspired streetwear: a black beanie, thin metal-frame glasses, and a high-collar or turtleneck layered under a heavy textured coat. Use soft, diffused natural lighting from above and slightly in front, with a cool temperature around 4800K, creating gentle shadows that sculpt the jawline and highlight the contours of the face without harsh contrast. Emphasize the velvety matte textures of the clothing and the subtle grain of the wall. Background remains static and uniform, allowing the subject's silhouette to stand out cleanly. Use a shallow depth of field with a medium portrait lens (50-85mm) to maintain crisp facial detail while softly separating the subject from the background. Color palette rooted in deep blacks, muted grays, and natural skin tones. Mood calm, intimate, and urban-modern, with a clean editorial aesthetic.
