喜怒無常的黑白商場肖像，帶有強烈的

"A moody black-and-white portrait of a young man with thick, soft, tousled dark curly hair falling over his forehead, gazing off to the side with a calm, aloof, slightly serious expression and his chin slightly lifted. He sits relaxed on a railing ledge, leaning back with both arms resting at his sides, one hand loosely holding a smartphone at the bottom edge of the frame. He wears a black cotton button-up shirt with a spread collar, the top buttons undone, sleeves rolled to the elbows, and a small embroidered logo on the chest, paired with black trousers. The setting is a multi-level shopping mall interior at night, with glass balustrades, metal handrails catching streaks of light, storefronts, and upper-floor walkways softly blurred behind him. Low-key ambient lighting with cool reflections along the railings, high-contrast monochrome tones with deep blacks and silvery greys, subtle film grain, natural skin texture, candid fashion-editorial street style, shot on a smartphone, vertical 4:5 aspect ratio, three-quarter body framing, sharp focus on the face."
Tips:
Add "photorealistic, cinematic black and white, soft film grain" for a more polished look.
For more drama, add "high contrast, deep shadows, urban night atmosphere."
To avoid brand issues, replace the chest logo with "a small minimal embroidered emblem."
