Impressive. It's like Naboo crossed with Budapest, only even more covered in ornaments. The roof tiles have a fairly dynamic pattern, so it sorta relieves the visual weight of the domes.
However, the building to the right seems a little off – perhaps a little too encumbered for something streaming to the heavens. Perhaps something less rusticated would be better fitting?
As another commentor said, the clouds. The lighting and the clouds. Makes me wonder, are they even taller buildings than seens, or just built on a really high place?
roofs look like the one of old churches. This old touch is a bit in conflict with those spaceships.
But it works all still very good together.
It's a epic work
