赛博朋克风格写实3D渲染，主体为机械义足，义足关节部分为带使用划痕的拉丝银色金属结构，可见圆形固定螺栓、外露的金属液压传动杆、多色排线与带芯片的裸露电路板，足部主体外壳为黑色碳纤维网格纹理，外壳表面分布着亮粉紫色流动电光纹路，义足外边缘带有粉紫色与青蓝色的霓虹光晕，放置在深灰渐变的纯色背景台面上，台面反射出义足投射的粉紫色柔光，采用平视中近景拍摄，焦点集中在义足的金属关节与发光纹路区域，四周留有充足负空间，冷调霓虹柔光照明，突出金属磨损质感与碳纤维纹理，1:1方形画幅，整体科幻工业风格。

Cyberpunk style realistic 3D render, the main subject is a mechanical prosthetic foot. The prosthetic joint part is made of brushed silver metal with usage scratches, visible round fixing bolts, exposed metal hydraulic transmission rods, multi-color wiring harnesses and bare circuit boards with chips. The main shell of the foot is black carbon fiber grid texture, with bright pink-purple flowing electric light patterns distributed on the shell surface. The outer edge of the prosthetic foot has neon halos of pink-purple and cyan blue. It is placed on a dark gray gradient solid background table, which reflects the pink-purple soft light projected by the prosthetic foot. Shot at eye level in medium close-up, the focus is on the metal joints and glowing patterns of the prosthetic foot, with ample negative space around. Cool neon soft lighting highlights the metal wear texture and carbon fiber texture, 1:1 square frame, overall sci-fi industrial style.
