mechanic in overalls 3d model

Create a highly detailed 3D character model of a professional mechanic wearing green overalls. The overalls should have realistic fabric texture, visible stitching, slight wrinkles, and subtle grease stains for authenticity. The mechanic is wearing work gloves and sturdy safety boots. The character is posed naturally as if carefully applying a decal, holding a small squeegee tool in one hand and a partially peeled decal sheet in the other. Expression should be focused and professional. No background, no environment — clean studio setup with neutral lighting. Style: photorealistic, high-poly, PBR textures, realistic skin shading, detailed fabric normals, clean topology suitable for animation and rigging. Output: full-body 3D character model, centered, isolated, studio lighting, 4K quality.
