Night Urban Staircase Fashion Portrait with Katana AI Image Prompt

Create a cinematic vertical fashion portrait of a single young woman at night on an urban overpass staircase. She has a cute but cold high-fashion presence, pale skin, delicate slightly mixed-race facial features, large soft eyes, and long {argument name="hair color and style" default="black, slightly wavy, voluminous hair"} falling around her shoulders. Shoot from a dramatic low angle looking upward, making her appear dominant and dangerous. She wears a {argument name="outfit" default="black belted long trench coat over black shorts, sheer black tights, and glossy black high heels"}; the coat opens and flows downward like a cape. She holds one large katana vertically in front of her body with both hands, blade and scabbard aligned toward the camera, covered with subtle handwritten symbols, bright silver highlights, tiny sparks, and glowing reflections along the edge. Her expression is calm, cool, slightly melancholic, and fearless as she looks directly into the camera. The setting is a dark industrial city pedestrian bridge with metal railings, concrete stairs, graffiti-covered walls, distant building lights, and a hazy black-gray sky. Use a black, charcoal, and cold blue color palette, strong editorial lighting, hard rim light from the upper left, high contrast shadows, realistic skin texture, glossy fabric reflections, shallow depth of field, and a premium urban dark fashion magazine aesthetic. No extra people, no readable brand logos, no watermark, no gore.
