Photorealistic Dragon Resting in a Desert Oasis

A photorealistic dragon perched at the edge of a crystal-clear oasis in a sunlit desert. The enormous dragon has iridescent emerald-green scales, sharp horns, and tucked-in leathery wings. Its amber eyes gaze over a tranquil pool, whose surface mirrors the dragon and the bright sky. Surrounding the pool are lush palms, reeds, and grasses, with golden sand and distant rolling dunes. Soft heat haze rises from the sand as light refracts through the air; ripples disturb the water, and the dragon's snout is wet from a recent drink. The scene is rendered in ultra-realistic detail with cinematic lighting, 8k resolution, and macro-scale texture on the scales, capturing every scale edge, pore, and reflection.
