Wyvern Lair: Photoreal in a Mountain Cave

Photorealistic wyvern inside a jagged mountain cave. The two-legged dragon-like creature sits on a slick rock ledge, wings folded along its back, long tail curling around a stalagmite. Emerald-green scales with a metallic sheen and faint black runes along the spine. Glowing amber eyes, sharp horns, and serrated teeth. Cold blue light pours from snow-filtered shafts overhead, creating volumetric rays and dust motes. The cave walls are rough and wet with mineral moisture; stalactites hang from the ceiling, stalagmites rise from the floor; a narrow underground pool reflects the wyvern's looming silhouette. Mist swirls around its snout as it exhales a warm breath. Subtle reflections shimmer on the water; the air is chilly with hints of earth and sulfur. The scene is shot with a cinematic lens, 50-85mm focal length, shallow depth of field, ultra-detailed scales, claws, and wing membranes; color palette cool blues and grays with contrasting warm gold from eye glow and breath; dramatic soft lighting, high realism.
