【解剖学骨架锁定】
人物必须遵守真实成年女性人体解剖结构。先生成稳定骨架，再生成衣服和装饰。头部、颈部、胸腔、骨盆、双腿和双臂必须连接在正确位置，不允许衣服褶皱替代肢体结构。

脊柱保持自然 S 形，身体轻微前倾约 3–6 度，不塌腰，不折腰。肩线自然水平，允许轻微倾斜，但左右肩不能错位。骨盆保持稳定，只有轻微步行动作带来的自然倾斜。

画面左侧前腿为主要支撑腿，大腿从髋关节自然向下连接，膝盖接近伸直但不反弓，膝关节弯曲约 3–8 度，膝盖方向与脚尖方向一致。小腿垂直向下，脚踝自然承重，脚掌平稳落地，不扭脚，不断踝。

画面右侧后腿为迈步中的摆动腿，髋关节轻微后伸，膝盖自然弯曲约 15–25 度，小腿向后下方延伸，脚尖轻触地面。后腿膝盖、脚踝、脚尖保持同一运动方向，不内扣，不外翻。

双臂从肩关节自然下垂，手肘轻微弯曲约 5–15 度，腕关节放松，手指自然半弯，不出现多余手指、断腕、反向手肘。所有关节只能沿真实人体可活动方向弯曲，禁止橡胶手臂、反向膝盖、错位髋关节、漂浮脚、融合肢体。

如果你用的是偏英文理解更强的生图模型，我建议直接用英文版，因为“joint angle、weight-bearing leg、pelvis alignment、knee-to-toe alignment”这些词比中文更容易触发人体姿态知识：

Anatomical pose lock: generate the human skeleton first, then place clothing and accessories over the body. Full-body adult female anatomy must be structurally correct. The head, neck, ribcage, pelvis, hips, knees, ankles, shoulders, elbows and wrists must be connected in realistic positions.

Natural S-curve spine, slight forward lean of 3–6 degrees, stable ribcage, no broken waist. Shoulder line is mostly level with only a subtle natural tilt. Pelvis is stable with a slight walking tilt, not twisted unnaturally.

Screen-left front leg is the weight-bearing support leg. The thigh connects naturally from the hip socket, the knee is almost straight but not hyperextended, knee flexion around 3–8 degrees. The knee points in the same direction as the toes. The shin drops naturally downward, the ankle bears weight, the foot is planted on the ground, no twisted ankle.

Screen-right rear leg is the trailing step leg. The hip is slightly extended backward, the knee is naturally bent around 15–25 degrees, the lower leg extends backward and downward, the toes lightly touch the ground. The rear knee, ankle and toes follow the same movement direction, no inward knee collapse, no outward foot twist.

Both arms hang naturally from the shoulders. Elbows are slightly bent around 5–15 degrees, wrists relaxed, fingers naturally curved. All joints must bend only in anatomically possible directions. No reversed knees, no hyperextended elbows, no broken ankles, no dislocated hips, no rubber limbs, no fused limbs, no floating feet.

然后你再把它接到画面主体后面。比如针对你这张图的完整提示词，可以写成这样：

一张高质感全身时尚写真，一位成年女性模特，黑色荷叶边无袖上衣与黑色多层蕾丝短裙，白色及膝袜，白色高跟凉鞋，黑色长直发，右侧发间有白色蝴蝶结。干净浅色棚拍背景，柔和高调光线，轻微俯拍视角，人物从画面上方向画面下方自然迈步，身体优雅、轻盈、真实。

【解剖学骨架锁定】
先生成稳定人体骨架，再生成衣服、蕾丝、袜子和鞋子。全身必须可见，头颈、肩膀、胸腔、腰、骨盆、髋关节、双腿、双脚、双臂、双手全部连接正确。脊柱保持自然 S 形，身体轻微前倾约 3–6 度，肩线基本水平，骨盆稳定，不能扭曲。

画面左侧前腿是主要承重腿，大腿从髋关节自然向下连接，膝盖接近伸直但不反弓，膝关节弯曲约 3–8 度，膝盖方向与脚尖方向一致，小腿自然垂直下落，脚踝稳定承重，脚掌真实接触地面。

画面右侧后腿是迈步中的摆动腿，髋关节轻微后伸，膝盖自然弯曲约 15–25 度，小腿向后下方延伸，脚尖轻触地面，后腿膝盖、脚踝、脚尖保持同一运动方向，不内扣，不外翻，不断踝。

双臂自然下垂，手肘轻微弯曲约 5–15 度，手腕放松，手指自然半弯。衣服的蕾丝边缘必须覆盖在真实身体表面，不能改变大腿、腰部、手臂和膝盖的真实结构。袜口必须贴合真实膝上位置，不能把袜口画成第二个膝盖。鞋子必须服从脚掌方向，不能改变脚踝角度。

真实摄影质感，皮肤自然，布料轻薄透明但结构真实，裙摆随身体运动自然展开。

负面提示词一定要单独写，而且要写得狠一点。尤其你这种腿部露出、袜子明显、裙摆遮挡大腿的图，负面提示词要重点压“反膝盖、断脚踝、双膝错向、腿融合”。可以这样写：

负面提示词：
bad anatomy, wrong anatomy, broken body, broken waist, dislocated hips, twisted pelvis, reversed knee, hyperextended knee, inward-collapsed knees, knees pointing away from toes, broken ankle, twisted ankle, floating feet, fused legs, extra legs, missing leg, rubber limbs, deformed arms, reversed elbow, broken wrist, extra fingers, missing fingers, duplicated joints, impossible pose, clothing replacing body structure, skirt edge mistaken as thigh, sock edge mistaken as knee, distorted full body, unnatural walking pose, doll-like stiff pose
