That's a glorious scene. Is the rather turquoise sky towards the right genuine? It looks odd.

I agree, and you must have been there on a beautifully clear day when you took this shot, which for every time I have been there (3) it was very blue, very hazy and cloudless, which can work for some shots, but with the width and depth of the canyon, it didn't seem to be working for me when I was there - and yes I have to agree with Jeremy about the colour of the sky to the right, so perhaps a little tweak in that area to shift the colour back to blue might not go a miss, but other than that tiny niggle, it is a lovely shot and makes me want to go back and try shooting it again for a fourth time
