Crystal Plateau Concept Art in a Cavern

An expansive plateau carved inside a colossal crystal cavern; concept art style, wide cinematic panorama. Bioluminescent crystals glow in cyan, teal, and magenta, refracting light into prismatic facets that illuminate the plateau and jagged rock edges. Hanging crystal stalactites crown the ceiling; dust motes drift in an atmospheric glow. The ground blends smooth mineral surfaces with shard-like crystal formations catching highlights. A lone traveler stands at the edge to convey scale, dwarfed by crystalline arches and towering walls. The scene fuses real cavern geology with fantastical, otherworldly design, rendered with painterly, high-detail textures suitable for matte painting. Lighting is soft yet dramatic, backlit crystals creating silhouettes and long shadows; depth enhanced by atmospheric perspective. Color palette: cool blues and purples with warm gold accents. Style cues: concept art, cinematic, sci-fi/fantasy, high detail, 3D-rendered feel with painterly brushwork.
