Whale in the Underground: Surreal 3D Tunnel Scene

Hyper-detailed photorealistic 3D render of a colossal whale swimming through a damp underground tunnel network. The tunnel walls are concrete with rusted rails, water pooling on the floor, and wisps of steam rising. Bioluminescent moss and fungi cling to the walls, casting a ghostly blue-green glow and creating volumetric fog that envelops the whale. Behind the whale, the tunnel narrows into a distant, dim corridor. The whale's skin shows subtle subsurface scattering and moist reflections; barnacle-like textures on fins and baleen. Cinematic low-angle wide shot with dramatic lighting, high dynamic range, and soft caustics on wet surfaces. The scene blends surreal fantasy with industrial subterranean architecture to evoke awe and mystery.
