天桥上的都市男装肖像

A natural-looking street fashion portrait of a {argument name="subject" default="young Japanese man"} standing on an urban pedestrian overpass in daylight, framed vertically from mid-thigh to head. He is leaning casually against a worn green metal railing with one hand in his coat pocket, body slightly angled, giving a relaxed but stylish candid pose rather than standing straight. He has medium-length wavy tousled hair in {argument name="hair color" default="dark brown"}, soft volume around the ears and forehead, and a slim build. Dress him in layered neutral-toned winter fashion: an oversized wool coat in {argument name="coat color" default="taupe beige"}, a chunky knit crewneck sweater in {argument name="sweater color" default="cream"}, and a long striped button-up shirt peeking out at the collar and hem. The mood is calm, refined, and contemporary, like a Japanese men's fashion editorial. Use soft natural sunlight with realistic skin tones, subtle shadows, muted colors, and shallow depth of field. In the background, show out-of-focus mid- and high-rise city buildings, bare winter trees, and a pale bright sky, creating a realistic Tokyo-like urban atmosphere. Photorealistic, understated color grading, detailed fabric texture, editorial composition, no dramatic effects, no text overlays, no extra people.
