3D渲染卡通风格拟人化奶牛角色欢乐形象插画

An adorable 3D cartoon cow character wearing a vibrant red baseball cap and dark green canvas apron, side view 45-degree angle, looking up at viewer from below with bright, curious sparkling eyes and a mischievous grin (no tongue). Enormous spherical head (over half of body size), tiny chubby body, classic black and white patches visible on legs and neck above apron. Stubby limbs. Top-down perspective, bird's-eye view. Pixar-style 3D render, soft matte textures on fur, textured canvas fabric on apron, subtle subsurface scattering, studio lighting. Pure solid white background, absolutely no shadows, no environment, no text. High detail, 8k resolution, octane render.
