I see quite a few bugs (misaligned brushes) and logic errors (such as the waterfall should have emptied a long time ago). Also, the layout looks like it was ripped off of ESF_Guru. The water should be clear, the sword looks randomly placed, and the terrain style looks very shoddy and poorly done. There looks to be many places to get trapped in where you must fly out which I find annoying. My suggestions are to try and smooth out the terrain, pick one or two types of trees that have the same color leaves, and fix the misaligned brushes.
