Vast alien city by a turquoise futuristic ocean shore

Gargantuan alien city with iridescent, smooth, curvy, bulbous buildings, adorned with glowing accents, resting on the shores of a vast, turquoise ocean, with slender, high towers serving as space ports, receiving large, metallic spaceships, under a light blue sky with unusual, wispy, feathery clouds and a prominent, light brown, cratered moon, in a style blending Chris Foss's vibrant, cosmic architecture, Syd Mead's futuristic, neon-lit landscapes, and H.R. Giger's intricate, biomechanical designs, with intricate details and textures.
