Futuristic Ring Megacity on Alien World

Cinematic concept art of an immense futuristic megacity built inside a colossal [circular ring megastructure] embedded in a [rocky alien landscape]. The massive ring dominates the skyline, thousands of meters tall, covered in intricate industrial panels, docking bays, glowing maintenance lights, and weathered metallic textures. Massive capital spacecraft, carriers, and small shuttles drift through storm-filled skies around the structure. Foreground: A [lone astronaut] in a detailed hard-surface EVA suit stands on a rain-soaked industrial platform overlooking the metropolis, providing scale. The platform features reflective wet metal, exposed cables, antennas, pipes, illuminated landing pads, and puddles. The city below is an ultra-dense cyber-industrial metropolis with towering spires, infinite buildings, atmospheric haze, rising smoke plumes, volumetric fog, and millions of tiny glowing lights stretching into the distance. Lighting and Atmosphere: Dramatic overcast sky with breaking storm clouds revealing shafts of sunlight, casting volumetric god rays over the ring and city. Cold blue-gray color palette contrasted with subtle amber and orange industrial glow. Camera: Wide-angle 24mm lens, low elevated viewpoint positioned behind the astronaut, centered composition with the ring framing the sprawling city, deep depth of field, hyper-realistic hard-surface sci-fi architecture, weathered materials, and atmospheric perspective.
