I like the colors used as well as the layout. I think you could improve this build by increasing the view distance. There are a lot of things in the air, none of which I was able to see clearly. I also think you could make the animation smoother on some of the rotating objects as well as making the hovering board in front of the big building have more of a hovering animation and not a bouncing one. The arms at the top of the builds seem to show no purpose but just waving around, I would try to think of something for them to do. Lastly, there is a lot going up in the sky, but I think the floor feels a tiny bit empty. Great job so far!
