Floating City and Flying Saucers

A colorful, sprawling, futuristic alien city floats serenely in the upper atmosphere. Gilded deep-purple arched towers and interconnected green red orange geometric polyhedra are bathed in the soft, diffused light of the planet's colorful glowing aura. Spacecraft hum above and around the city. Lush, vertical green gardens with blue flowers and orange fruits cascade down the sides of glittery futuristic buildings, creating a harmonious blend of pretty nature and advanced architecture. The style is bold, detailed, clean, utopian future concept art, inspired by the science fiction architectural visions of Syd Mead and the surreal fantasy landscapes of Roger Dean.
