This is lovely, just my kind of image. Well spotted.
If I was being incredibly picky (which I am) the dark clouds help to balance the image nicely with the mountain at the bottom and sort of 'close it off'. I might be tempted to crop a tiny bit more from the top or clone out the bit of orange sky that is visible on the very top right.
Again though, that might just be me and it is really great in any case.
