This is one of the better photos of Cathedral Rock that I've seen. Very nice composition. The only thing I question is that the sky looks as though a polarizer was used on a wide-angle lens--the left side of the photo would be at about 90 degrees from the sun, and the right side approaching 180 degrees.
Sedona is a wonderful place for those red earthy tones and of course the light at sunrise/sunset accentuates these attributes. Because I live in Arizona my opinion may be biased a little, but I think that this is a great shot. Keep up the good work.
