Very nice example of the ROT, good entry for the challenge.
The colors in the sky are a little dull for me, I wish they "popped" a little more. The detail in te foreground is really good. The lines of the mountain lead the eye RIGHT to a ROT intersection, which is perfect.
I think you could have cut out a lot of the sky. It takes over the picture. With cropping, you could still have gotten a good picture in a landscape format.
