I really like the blue filter you applied here and would love to see it bigger. The background has enough light to still see the outlines of the peaks and valley and nicely blends in with the colors of the rising sun. As an alternative, and not saying it would be better, but maybe try keeping the image that is inside the cave you are shooting from in it's natural warmer light? Also, maybe brighten a little? Very nice shot though and post processing. I appreciate seeing images in a different light.
Matt this is indeed very unique and I would even say courageously bold. Not once have I ever seen a classic American southwest visa portrayed in the hues that exist on the oppposite side of the color wheel. Kudos to you for putting this out there. I think that with enough exposure it would really grow on me - it just stands out so much from the norm.
