It is so hard to shoot a cloudy sky with out having it blow out. HDR here would have been really nice to pull out the clouds, and enhance the shadows in the snow on the ground. I like the composition. BW work fine here.
Wonderful scene. I'm curious what it would look like cropped in a little more, especially since you're cutting off the top of the front right tree anyway, it seems that the extra sky and trees don't add that much and the broken building is so interesting.
