Post-apocalyptic sci-fi utopian mega-city concept AI Image Prompt

Surreal futuristic, sci-fi utopian city, post-apocalyptic wasteland style, world's end, aerial building complex, colossal scale, megalophobia, extremely brilliant, grand-scale environmental concept design, hard sci-fi + architectural fantasy, hyper-realistic rendering. The image depicts a super-large futuristic ring-shaped mega-structure occupying most of the frame: the building volume dominates the composition, with huge curved structures extending vertically from the right side, wrapping upward and outward to create a strong sense of spatial oppression and scale shock. Massive city scene, rendered with Unreal Engine 5, dense city, maximalism, high detail, giant city, with vehicles shuttling endlessly and spacecraft flying back and forth in the air, top-down perspective revealing more details, high contrast, high-definition image, only the edges of the frame showing sky. Extremely rich composition, maximalist, with dense modular building units, curved frameworks, and layered floating platforms forming a deep vertical city interior space. The building interior features neighborhoods, observation terraces, public activity areas, and ecological green belts, with tiny figures scattered as scale references to emphasize the grandeur of the mega-structure and human insignificance. The external sea of clouds and aircraft are compressed to secondary areas, serving as foils and spatial extension. Overall composition uses ultra-wide-angle top-down and oblique perspective, with architectural curves guiding visual flow. Lighting is dominated by cool natural daylight, combined with volumetric light from high-altitude clouds and warm point lights inside the building, creating a rational, cold, grand, and futuristic utopian sci-fi atmosphere, showcasing high-density detail, cinematic composition, and hyper-realistic AI environmental concept art. Ultra-wide-angle, top-down + oblique perspective, strong depth, architectural curves guide the eye, natural daylight, volumetric light from clouds, warm point lights inside, creating a calm, rational, and grand sci-fi utopian atmosphere. Extremely high detail density, hyper-realistic, 8K-level environmental concept design and high-end AI digital art. Ultra-high resolution, extreme detail, photorealistic rendering, concept art level. Warm tones (brown and earth tones), natural sunlight from upper left, reflected light on buildings, local warm lights illuminating the city interior, strong atmospheric perspective, ruins, dust, haze.
