Like this very much, cause it is somewhere between photograph and illustration, cloud looks almost original, trees and fence have so much detail. Compositionwise I think the cloud shouldn't be cropped - can you move it a little down and left?
You really nailed the exposure on this one. Great balance between the sky and the ground. There are technically two problems I can see with this shot. One is that the subject is too centered and the other is that the subject isn't clear enough. The trees on the right distract from the dead tree in the middle as do the trees in the background. GREAT exposure though.
