Rooftop Cave - Surreal Concept Art on a Rainy Skyline

Ultra-detailed concept art of a sprawling cave integrated into the rooftop of a rain-soaked city building at twilight. A yawning cavern opens from the rooftop edge, with jagged stalactites, glowing bioluminescent fungi, and a shallow stream feeding into a metal drain. Neon signs and city lights reflect off wet concrete and rock, casting vibrant colors across railings and a rusted ladder that lead into the cave mouth. Distant skyscrapers loom through fog; rain droplets hang in the air; dust motes drift in subtle beams of light. Style: cinematic, painterly concept art for a video game, with strong perspective, dramatic lighting, high-detail textures, and a blend of natural cave textures with urban rooftop materials. Palette: cool blues and purples illuminated by warm amber highlights.
