Underground Cavern with Cascading Waterfalls and Luminescent Water

Digital rendering depicting subterranean environment with multiple tiered waterfalls descending approximately 60+ meters vertically. Composition utilizes volumetric light scattering through dense vegetation canopy. Water basin exhibits bioluminescent properties with cyan-blue coloration. Rock formations display columnar basalt characteristics. Atmospheric particulates and mist diffusion create volumetric density. Vegetation coverage estimated at 70-80% of frame perimeter. Lighting employs directional key source from upper left quadrant with ambient fill.
