Coral Cavern Reef — Underwater Concept Art

An expansive coral reef inside a submerged cave, concept art for a fantasy underwater environment. Warm and cool bioluminescent corals glow against rugged cave walls with stalactites and stalagmites, shafts of sunlight filtering through cracks and creating volumetric light beams. The reef features brain coral, branching staghorn, sea fans, tube sponges, and neon polished anemones in electric blues, pinks, oranges and purples. Schools of tiny fish weave through the reef while a larger silhouette of a reef fish or manta glides past. Soft particles hover in the water, bubbles rise from unseen vents, and gentle currents ripple across textured rock. The composition is a wide cinematic shot near the floor focusing on a glowing coral arch as a focal point, with painterly concept art style textures, high detail, and a moody blue green palette with vibrant accents. Style is cinematic painterly 3D rendered video game concept art.
