I think it looks awesome. There are a couple small things that could be changed but they aren't really all that important. The left little fairy's shape to me gets confused with the fay's wing. so maybe erase a branch of the wing or something? no biggy. another thing is perhaps make the lower left and lower right foreground elements filled in more. just shade 'em in more and only have them have a little bit of rim lighting and it will add more depth. Other than that. this is kick butt! and i think you should put it on something and sell it!
Hurm, yes, I see what you're saying. I think I can fix that little fairy easily enough.
As to the foreground elements... I might be able to work on them more a little later - bring some more shadows in. My problem there was that I got so very fed up with trying to bring so much detail into a monotonous subject. The uprooted tree is actually full of little 'root sprites' which also made it difficult to shade properly around.
I think I may change the silhouetted leaves on the bottom as well. They seem out of place. Perhaps I'll change the type of leaf to a more bush-like setting.
