Photorealistic 3D Cow in Ancient Ruins at Golden Hour

Photorealistic 3D render of a calm cow standing in an ancient archaeological site. The scene features weathered stone ruins: towering columns with chipped capitals, a crumbling temple wall, and a dusty ground scattered with pottery shards. The cow is realistic with a white coat and black patches, fur detailed, with dirt on its hooves. Warm golden-hour light from the left creates long shadows, soft volumetric dust, and gentle haze in the background. Depth of field keeps the cow in sharp focus while the ancient structures fade softly. Textures include rough limestone, moss, and aged plaster, with subtle weathering on artifacts like a broken statue head nearby. A few archaeologists in safety gear can be seen in the distance for scale. Camera at knee level, slightly off-center to the left; composition follows the rule of thirds. Render style: ultra-detailed, PBR shading, global illumination, ambient occlusion, and realistic shadows.
