Post-Apocalyptic Ruined City 3D Concept

Full prompt

A grim, oppressive post-apocalyptic cityscape opening onto a palette of desolate ash-grey tones. The broken structural skeleton of a once-thriving metropolis stands decaying beneath heavy atmospheric haze. Abandoned train tracks are contorted and fractured as if twisted by a colossal hand, their exposed steel rails sprawling across the wasteland like desiccated veins. Shattered train carriages lie pulverized in the dust, faintly reflecting sickly, cold shards of ambient light. High-end 3D cinematic render with dark dystopian atmosphere, deep scale, gritty textures, and a crushing sense of dread, vertical 9:16 composition.
