Composition/use of frame space - this is a very solid composition. I particularly like the way that the ridgeline is matched by the clouds.
Colors/White Balance - WB looks great - though the colors, particularly at the bottom of the canyon, look a bit unsaturated as compared to the rich blues and warm colors above. Very nice though.
Exposure - I can see how tricky a shot that this was to capture. I think you did a great job.
Creative use of Aperture/Shutter - NA
Perspective - NA
Creativity - Very nicely done. I am told that you can go to Bryce and shoot a thousand rolls of film and still not have enough.
Emotion - I would say that this image shows scale in a serious way. It provides a sense of microcosm.
Forethought/Visualization - Well visualized, I am not sure how to photograph it differently... I would be very interested to photographing some of the rock structures more tightly. However, that is for a different day. This photo is nicely framed.
Post processing - Again, you did a nice job work with the dynamic range issues of the photo. It might be nice to see a bit more saturation in the bottom of the photo, but honestly, it looks better than fine.
Thanks for sharing. Nicely done.
