New Engine / Models&levels needed

Here is my xonnel engine. http://www.sinc.sunysb.edu/www/stu/lbantoin/ I have 4 new screenshots up showing off the new terrain system with incorporated architectures. I do however need a new level, because the one I have in there sucks. If you have any level designing skills and want to make a level for me, it would be appreciated. Right now I am using map files from worldcraft, but I can adapt to whatever you can produce. I also need models like trees and stuff for the terrain. Any help?
