Ok first, off this is really good. It looks like a concept art you would find in some gaming book. You added shadows in the update, but I think it looks better without it(opinion) I say you should update the cracks in the rocks. They look like random lines and its very noticeable to the eyes. Try blending it in abit. Other than that I really like what you got here. specially the fog and the eclipse. It gives it that good feel of distance.

This comment is behave of both this and the updated one.
