This is excellent. I don't know if the "Right" tilt was intentional, but after correcting it, I still liked the overall image either way. The only improvement is to crop off about half the sky. It then gives the landscape the impact it deserves.
nice capture of the sky, it really deserves the area you gave it. The colors are a bit on the blue side, though, you might want to warmify them, say in Picasa, to make it look more natural.
