Cheetah in a Crystal Cave, Photorealistic

Photorealistic cheetah prowling through a vast crystal cave. The walls and roof are lined with towering quartz crystals that glow with a cool blue and emerald light, their facets casting prismatic reflections across the scene. The cheetah is mid-stride, muscles tense, golden-tawny fur with bold black spots rendered in ultra-high detail; each hair visible, whiskers and dew on the nose, amber eyes sharp and focused. Crystalline stalactites hang from above; mineral dust swirls in a soft beam of light, creating sparkling specks on the fur and a rain of glittering reflections on the wet rock. Ground covered with crushed crystals. Lighting is HDR and cinematic, camera angle low to the ground, 50-85mm equivalent, f/2.8, shallow to medium depth of field to keep both cheetah and foreground crystals in crisp focus, 8K resolution, photorealistic textures and realistic shadows.
