Underwater Metropolis

A vibrant underwater cityscape, where coral structures mimic skyscrapers, and schools of glowing fish swim through streets of colorful reefs. A diver in a sleek suit explores this bustling metropolis, with bubbles rising to the surface. Above, the water's surface shimmers with reflections of a sky filled with stars and a glowing moon. The style is vivid and imaginative, combining elements of marine life with futuristic architecture.
