Underwater Cave Centaur in Bioluminescent Light

A hyper-detailed digital painting of a centaur gliding through an underwater cave. The centaur has a humanoid upper body with flowing hair and ornate armor, and a sleek, scaled horse lower body with a finned tail and webbed hooves. The cavern walls are encrusted with bioluminescent corals, glowing anemones, and swaying kelp. Soft blue-green light filters from an opening above, creating dramatic shafts and shimmering reflections on the centaur's scales and the rocky formations. Bubbles rise as the creature swims, sand swirls on the cavern floor, and distant jellyfish drift by. The mood is magical and awe-inspiring; cinematic lighting, ultra-detailed textures, painterly digital art style, high-resolution, 3D-rendered realism.
