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.

背景设定：{argument name="alley style" default="一条狭窄的复古波普风后巷"}，带有生锈的卷帘门、剥落的油漆、褪色的淡彩墙面、贴满贴纸的金属板、色彩鲜艳的塑料板条箱、老式自动售货机的微光、霓虹灯碎片、手绘招牌、积水以及裸露的管道和磨损的混凝土。空间应呈现出粗粝感，但在城市衰败的背景下，视觉上要充满活力，并叠加强烈的波普色彩点缀。 构图锁定：紧凑的 4:5 竖构图时尚大片剪裁，采用从胫骨到膝盖高度的低角度近摄，而非全身目录照。主体占据画面的 80%–90%。前景中的一只膝盖、躯干、肩膀、双手和面部占据画面主体。小腿、脚部或画面边缘可进行刻意裁剪。保持生锈的卷帘门、贴纸、色块和巷道纹理在主体后方可见，作为压缩的视觉标识。 姿势锁定：主体不得站立、行走或随意倚靠。她栖息在 {argument name="seat object" default="堆叠的彩色塑料板条箱"} 的最边缘，旁边是生锈的卷帘门。她的臀部靠近板条箱边缘，而非深陷在座位上。一只膝盖在画面中下部的前景处高高隆起，急剧弯曲以勾勒出躯干轮廓。另一条腿沿板条箱线条或路面垂下，可部分裁剪。她的躯干从臀部开始略微前倾，同时保持脊柱挺直。双肩不对称且略微倾斜。一只前臂自然地横放在抬起的膝盖上，另一只手放在腰部或大腿上部，以保持服装线条的利落。下巴微收，眼神看向画外，展现出 {argument name="expression" default="冷静的时尚自信"}。 避免：站立姿势、全身构图、游客照姿势、随意坐姿、可爱的双手合十姿势、遮挡身体的杂物、低角度导致的身体比例畸变。
