Alien Cave with Glowing Crystals

Act as a visionary sci-fi concept artist with 10+ years of experience in extraterrestrial landscapes. Create a hyper-detailed, otherworldly cave scene illuminated by bioluminescent [CRYSTAL_FORMATIONS] in [VIBRANT_COLORS], casting eerie reflections on [ALIEN_FLORA]. The composition should emphasize depth, with towering crystal spires, misty cavern corridors, and subtle hints of unknown alien lifeforms lurking in the shadows. Use a cinematic lighting style with high contrast between the radiant crystals and the inky darkness of the cave, evoking a sense of wonder and mystery. Render in 8K resolution with photorealistic textures, focusing on the interplay of light refraction through the crystalline structures.
