Neon Constellation in an Underwater Cave

Hyper-detailed digital artwork of an underwater cave where a luminous constellation is projected onto the cave ceiling and walls. The constellation is formed by bioluminescent algae and glowing mineral veins, with neon lines connecting stars. Water is clear with sun shafts filtering from above, refracting into prism-like reflections on stalactites, stalagmites, and coral. Tiny fish drift, bubbles rise, and jellyfish float near the cave roof. Color palette features deep blues and teals with electric cyan, magenta, and gold highlights. Style blends cinematic 3D render with glossy, glassy surfaces and digital glow effects, evoking synthwave cyber-art. Overall mood is serene, mysterious, and awe-inspiring, as if a star map has awakened beneath the waves.
