复古波普风巷道时尚大片

Background identity: {argument name="alley style" default="a narrow retro-pop back alley"} with rusty rolling shutters, peeling paint, faded pastel wall sections, sticker-covered metal panels, colorful plastic crates, old vending-machine glow, neon fragments, hand-painted signs, puddles, exposed pipes, and worn concrete. The space should feel gritty but visually lively, with strong pop color accents layered over urban decay.

Composition lock: tight vertical 4:5 fashion editorial crop, close low-angle camera from shin-to-knee height, not a full-body catalog shot. The subject fills 80–90% of the frame. One foreground knee, torso, shoulders, hands, and face dominate the image. Lower legs, feet, or side edges may be intentionally cropped. Keep the rusty shutter, stickers, color blocks, and alley texture visible behind the subject as compressed visual identity.

Pose lock: the subject must not be standing, walking, or casually leaning. She is perched on the very edge of {argument name="seat object" default="stacked colorful plastic plastic crates"} placed beside a rusty shutter. Her hips stay close to the crate edge, not deep on the seat. One knee rises large in the foreground near the center-lower frame, bent sharply to frame the torso. The other leg drops lower along the crate line or pavement and may be partially cropped. Her torso leans slightly forward from the hips while keeping a long spine. Shoulders are asymmetrical and slightly angled. One forearm rests cleanly across the raised knee, while the other hand is placed at the waist or upper thigh to keep the outfit line clean. Chin slightly lowered, gaze off-camera with {argument name="expression" default="calm editorial confidence"}.

Avoid: standing pose, full-body framing, tourist-photo posture, casual sitting, cute hand-clasp pose, clutter covering the body, distorted low-angle anatomy.
