Awesome! only thing i'm not too sure about is the tree, I dunno it just somehow looks like its just been put there and doesn't really have any relevance to the rest of the picture. but other than that i love it!
I totally agree with that to be honest. It's a custom brush. I just wanted to have something to create a sense of scale (and since humans can identify with trees quite well, I put that in there). Originally I was going to put in a guy walking somewhere but I was tired/lazy at the time so I didn't. :Y
