Cité futuriste sous dômes sur un vaste monde océanique alien

A Vast, wonderful, vibrant offworld space colony on a vast water planet. The city is several giant water domes connected by clear tubes linking the domes. Inside the domes are magficient cities. There is a tall tower in the distance that is the space port. The artwork blends Syd Mead's retro-futuristic aesthetic, Daniel Dociu's meticulous, industrial details, and Ian McQue's cinematic, epic scope.
