leuallen - I would have probably dodged the house a bit more. Right now my eye is drawn to the one line in the cloud that is really bright. While interesting, I don't think it really illustrates the full story of the scene. The scene is as much about this farm house that is weathering these changing conditions, so the house needs to grab a bit more attention. With it's midtone gray, it's there, but it has no life.
If you wanted it to be all about the sky, I would probably burn the house a bit darker, but I fear that would make the entire image feel too top heavy.
