I like the plants and the how the terrain is marked. I'm assuming you did something to the terrain to make it have the ridges, etc. Did you use TG2 for the terrain or create it some other way? The ground is very red, which I've seen before. Well detailed and good sun placement. Something about the rocks in the foreground look out of place...or plastic-like. Maybe some sort of scuffs, dirty, grungy can be applied to those.
