Portrait Mode Streetwear Devant un Mur de Graffitis

A moody full-body fashion portrait of [a young woman] standing in a narrow urban alley covered in dense, colorful graffiti, photographed at night with dramatic low-key flash lighting. She is leaning casually against the painted wall with one hand resting on a large pair of over-ear black headphones and the other hand tucked into the front pocket of an oversized [mustard yellow] hoodie. The hoodie is long enough to wear like a dress and features a simple black smiley-face graphic centered on the chest with white drawstrings. She wears a black backpack with two visible shoulder straps, white crew socks, and chunky black-and-white low-top sneakers. Her legs are bare, posing relaxed with one knee slightly bent and one foot set forward. Her hair is shoulder-length, slightly messy, and [dark blonde]. Vertical full-length composition from head to shoes, with the subject centered slightly left of frame. The background is a gritty wall dominated by turquoise blue, yellow, pink, and black spray paint with drips, tags, and abstract cartoon shapes. The dark ground is worn and reflective with paint splatters. High contrast, deep shadows, sharp focus on streetwear fabric and texture, editorial photography style with an underground nightlife vibe.
