I really love the drama in the background. The dark brooding nature of the cloud and snow - that sort of portentous stuff sings to me. I also really like the interplay of warm light on the trees which is well juxtaposed with the background.
I would however exclude the tufts of grass in the foreground that are detracting from the image at present. They cause my eye to dart back and forth and I cant settle on the beautiful color harmony between the warm trees and cool background.
BTW: this image is an excellent example of complimentary colour harmony. Nice work.
