Noir futuristic alien city rising above layered waterways

A noir style massive alien city with tall gleaming glass style buildings and smaller domed buildings built on many levels. There are curvy roads and bridges connecting it all together. Many parks are scattered around the city. The city is on the edge of a massive ocean with clear greenish water an and massive futuristic ships approaching huge piers. Space ships are flying high overhead. There is strange colored lush vegetation all around the city. There are two moons in the background off the horizon in the clear daytime sky.
