I really like the clouds in the middle of the picture. But the top 1/3, and bottom 1/3 of the image are to dark imo. Cropping out most of the top clouds (the really dark parts), and leaving just enough to keep the horizon line below center would greatly increase the look of this image.
I like the edit, but i almost would have cropped more off the top. I think a good crop would be a landscape one with the trees at the bottom of the picture and then crop a little above the bright clouds so you get the dark framing on top and bottom.
