Below is my current progress. The grass will probably get changed to sand and the light gray texture is supposed to be white marble but looks more like the moon's surface...

I'm not sure what I want to do with the textures. Don't know what I should do with the maze walls, either...

Next, I'm going to put trees and foliage and stuff in there. After that, top-down statues. If I change the grass to sand, I'll put some leaf-less tress in there and hold off on the shrubs.

At some point, I'm going to put a couple round, fountains in various places.

I'm really having a hard time finding textures and stuff. Any good suggestions?
