This is really wel done, I like it alot.
All of the plants and rocks look good.
The only complaint I can have is the sheer rock face, which could occur quite naturally in this environment, so it's notreally anything to complain about. Good work.
It's cool, no matter what other people say. I've seen lots of worse desert terrains (plain hill sanded only, or with some palms or bones - just without any fresh idea and conceptions you know), so I don't understand why it's score is that low. A piece of realism and spectacularity on the table either!
