Banshee of the Crystal Cave 3D Render

Ultra-detailed 3D render of a banshee manifesting in a crystal cave. A translucent, ethereal female figure with long flowing hair and tattered robes, glowing with pale blue-green light as she wails. The cavern walls are encrusted with quartz and amethyst, with sharp stalactites overhead and a tranquil, mirror-like pool reflecting the scene. Refracted light streams through crystal facets, creating vivid caustics and volumetric beams that cut through wispy fog. Use photorealistic materials: subsurface scattering on the banshee's ghostly skin, translucent hair, glassy crystal surfaces, and accurate global illumination. Cinematic lighting, depth of field, high detail, and a low-angle, dynamic pose that emphasizes the banshee's ghostly scream. Color palette: cool blues, icy whites, with subtle violet tints to enhance the otherworldly mood.
