Looks like a good park. You were able to add a lot of coasters and rides without getting it to look too crowded. But you do need to add some more theming, especially buildings. Needs improvement in that, and I got several messages saying that Guest 16592 is lost and cant find the park exit. That is unavoidable, but still annoying. Overall, I think this will place well in Premier Park voting if you add a little more theming.
EDIT: One other problem I noticed is a music problem. Nearly every ride has music, and that creates a bad sound.
