超写实赛博朋克3D渲染，特写构图，浅景深，画面主体为从右上延伸至左下的半机械义手，小臂外层为黑色碳纤维纹理外壳，表面分布亮粉色闪电状霓虹光效与青蓝色电路纹路，腕部与手掌内部为做旧银灰色金属骨架结构，露出银色液压传动组件、红黑相间的供电管线，每根五根机械手指的关节处内嵌青蓝色弧形发光灯带，指尖为尖锐的金属造型，背景为均匀的深暗近黑渐变纯色背景，冷硬金属材质带有细微使用划痕与磨损质感，霓虹光效自然溢出淡紫色边缘光晕，侧方冷光照明强化机械结构立体感，8K分辨率，高精度材质表现

Hyper-realistic cyberpunk 3D render, close-up composition, shallow depth of field, the main subject is a semi-mechanical prosthetic arm extending from the upper right to the lower left of the frame. The outer casing of the forearm is made of black carbon fiber texture, decorated with bright pink lightning-like neon light effects and cyan circuit patterns. The wrist and inner palm are constructed from distressed silver-gray metal skeleton, exposing silver hydraulic transmission components and red-black power pipelines. Each of the five robotic fingers has embedded cyan arc-shaped light strips at the joints, and the fingertips are sharp metal shapes. The background is a uniform dark near-black gradient solid color background. The hard cold metal material has subtle use scratches and wear texture. The neon light effects naturally spill out a pale purple edge halo. Side cold lighting enhances the three-dimensional sense of the mechanical structure. 8K resolution, high-precision material performance.
