Desert Dunes Inside a Subway Tunnel (3D Render)

Ultra-detailed cinematic 3D render of a subway tunnel transformed into a desert. Curved concrete tunnel walls with peeling paint and graffiti, rusted rails buried under wind-swept sand. Dunes rise along the trackbed, with hardy desert plants like cacti sprouting near the ballast. A battered, half-buried subway car sits to the side, its windows dusty and metal corroded. Sand swirls in illuminated dust motes as volumetric light beams cut through the tunnel from the distant daylight entrance. The tunnel mouth glows with hot sun, heat haze distorting the far end. Realistic textures: concrete, rust, glass, sand granules, and wet patches reflecting light. Global illumination, physically-based rendering, depth of field, and photorealistic shadows give a surreal yet believable scene. Low camera angle, slightly to the side, focusing toward the far end where desert spills into the tunnel for dramatic scale.
