Steampunk Griffin in a Steam Locomotive - 3D Render

A hyper-detailed photorealistic 3D render of a majestic griffin integrated into a steampunk steam locomotive. The griffin stands atop the brass-and-copper boiler, wings spread wide, feathers with metallic sheen and subtle patina. The machine features exposed gears, pistons, riveted plates, clockwork joints, and steam vents, all weathered with oil stains and scratches. Setting is a foggy railway yard at dusk with billowing steam and warm amber lighting. Materials include brass, copper, aged steel, leather harness, and glass lenses. Composition in a dramatic 3/4 view focusing on the griffin's head and chest while the engine looms in the background, shallow depth of field. Lighting is cinematic, with volumetric steam, rim lighting on the griffin, and subtle lens flares; render with ray tracing, high detail, and filmic color grading.
