Generation Stadium 1.0

Hey guys, I know it's been a while since I've posted, but you wouldn't believe how many projects I've been working on for the past few months. Anyways, here is one of them. This one took a particularly long time to make, and I would appreciate feedback to know how to make it even better. I got the inspiration on the base from a UFO, because it's supposed to look like a floating ship. The top is just a circular stadium with a hexagonal cage. I hope you enjoy!

P.S. There is a hidden sign for you to find.
