3D Rendered Cow in a Heavy Rainstorm

Ultra-realistic 3D render of a single cow standing in a heavy rainstorm on a rural pasture. Photorealistic CGI with physically based rendering: wet fur clinging to the body, droplets bead on the nose, eyelashes, and ears; rain droplets actively in the air and streaking down the fur. Ground is muddy with reflective puddles showing the cow and a gray, overcast sky. Lighting is cool blue-gray with a subtle rim light to softly outline the cow's silhouette. Camera at cow-level with a slightly low angle (about 45-50mm field of view), shallow depth of field so the background is blurred but the cow is razor-sharp. Materials include realistic fur with anisotropic sheen, wet mud on legs, and glossy water droplets. Wind direction suggested by fur and grasses; rain streaks diagonally across the frame, occasional splashes and ripples in puddles. Cinematic color grading with cool tones and light film grain; 8K-ready level of detail.
