Flash photography style: school hallway uniform photo

Create a gritty flash snapshot photo, set in a dim high school hallway, in 2:3 vertical ratio. In the frame, a teenage student wearing a Korean/Japanese-style dark school uniform appears full-body, leaning against a long wall of light blue-gray metal lockers covered with stickers, labels, tape marks, graffiti, and scratches. The subject is slightly right of center, one hand propped on the lockers, legs crossed, wearing , paired with black over-the-knee socks and black-and-white platform sneakers, with a glossy black shoulder bag with a silver chain on the shoulder. She has ; her face is deliberately treated with a square gray blur to hide her identity. The hallway extends deep into the background, with ceiling fluorescent lights, reflective gray floor tiles, scattered papers on the floor, and groups of students talking on the left, their faces also softened or blurred. The right edge includes a red fire extinguisher and a Korean emergency exit sign with a downward arrow. Use the raw texture of a 2000s digital camera: strong direct flash, cool tones, high-contrast shadows, slight noise, imperfect composition, authentic school clutter, rejecting over-retouching, creating a documentary-style candid atmosphere. Add a subtle watermark-like line of text in the lower left corner .
