Beautiful contrast between the motion in the sky and the razor sharp rock outcrops. Really nice balance to the composition too. I think many years of practice are required before I can manage a photo even half this impressive!
I love the red rock. But I am not a big fan of the streaked clouds. I think it gives the image a fake look (I know it's not though, although I've never done an exposure long enough to catch cloud movement like this- I understand how it's done.)
It is framed excellently, even the rock in the distance has the same window effect which really pulls this image off.
Holy sexiness. Love that pink cloud movement. Well done sir. As I was about to click off I noticed the other arch catch my eye...I say crop just to the right of that one so the eye doesnt get lost where it should stay
