Great shot David, I hope to see a few wild horse as I will be in New Mexico for a the first two weeks in November. Great background just a little tight.
The Cottonwoods make a beautiful BG . the Stallion looks as though he was posing for you. I don't think this needs to be sharper it's a portrait- and I think it shows the horse's strength in a very calming way. I like it alot!
