It doesn't get much better than this for a landscape. Here you have great composition and shapes forming the scape of the land. You have the curve in the foreground, the mountians forming a v shape in the midground and the excellent sky in the background. With all the awesome photos in this competition, this stands out as at least an honorable mention!
Quite interesting but the way it is processed the hills seem to have been overlain onto a background sky. I know it hasn't been but I think your sharpening workflow has had that effect.
