Great shot. If you are concerned about having too much sky in the upper left part of the picture, try cropping a copy of the photo to eliminate some of the sky and see if you like it better. It might improve it a bit, but again it may not.
Thank you, FotoPhreak. I am not too concerned about having too much sky. I did try a couple of different crops, and I stuck with this one. Overall, it just seemed to have a greater impact. Thanks for your suggestion.
