Well, the first problem I see, is that I don't see anything, so there is obviously an over-use of invisible objects, rides, and scenery. The other problem I see is that there is just waaaaay too much white, I mean, when you make everything white, it makes it hard to see anything there. Lastly, I see there is a lot of empty space that could be better used.
I think if these three areas are corrected, you will be well on your way to a really nice park.
