Build an original English-language image generation brief with the following direction.
Subject and setting: Film-inspired illumination. High detailed. The surrounding setting perfectly copies the scene: a modern steel-framed bridge with prominent criss-cross "X" metal pillars and side railings. She is posing confidently. Positioned upright on an outdoor pedestrian bridge walkway. A realistic head-to-toe photo of a young girl with fashion-forward hair.
Composition and styling: Styled with loose baggy black wide-leg denim jeans and clean white sneakers. She is dressed in an oversized white V-neck football jersey with the bold black number "20" printed on the front.
Lighting and camera: Leading towards distant soft-focused high-rise city buildings under a bright overcast sky. Looking straight at the camera with both hands casually tucked into her jeans pockets.
Output requirements: Realistic texture.
