Moody Nighttime Entrance Portrait.

"A moody, cinematic street-style portrait of a young man with short, thick black hair styled in a tousled, swept-back quiff, a neatly trimmed black beard and mustache, and a calm, slightly brooding expression as he looks straight at the camera with his head tilted slightly down. He sits on wide dark stone steps with his knees apart and his hands clasped loosely in front of him, wearing a silver analog wristwatch and silver rings. He wears a glossy black faux-leather bomber-style jacket with a spread collar and cream piping along the zipper, layered over a cream-white t-shirt, with a thin silver chain necklace. He pairs it with loose, wide-leg washed-black baggy jeans and green suede low-top sneakers with white stripes and cream soles. The setting is the entrance of an old heritage building at night, with a tall dark double door featuring ornate wrought-iron scrollwork grilles, dark paneled wood, and a large planter with a tropical leaf in the top-right corner. Low-key ambient lighting with soft highlights on the jacket and face, deep shadows, a dark palette of black, charcoal, and bronze with a pop of emerald green from the sneakers, natural skin texture, shallow depth of field, edgy urban fashion photography, shot on a smartphone, vertical 3:4 aspect ratio, full-body seated framing, sharp focus on the subject."
Tips:
Add "photorealistic, cinematic night street style, soft film grain" for a more polished look.
For a moodier feel, add "low-key lighting, deep shadows, subtle warm rim light."
To avoid brand issues, say "generic green suede sneakers with white stripes."
