Very interesting and original perspective. The silhouetted brush adds some interest, but on some level I think portions of it distract from the shape and form of the fin & arch that is so magically lit. I like the polarized effect. The red rock pops against the blue sky very effectively. Utlimately I think cropping a little off the top would reduce the brush silhouettes hanging on the top edge of the frame and better frame the arch. Just a thought.
