Great composition for this humorous portrait, my eyes jumped from one face to the other and to the Saguaro cactus and back again, it creates a rhytm, I can almost hear it. I like the lay-out of Your three subjects and great command of the depth of field, but lighting of the high noon sun is Les Miserables.
