I see you caught him mid-chew! Maybe not as appealing as he would be otherwise. ;-) Horses generally look better without halters, for what it's worth, especially one fit as loosely as this one. Hope to see more of this guy!
Tack sharp focus. Not too original but it's not easy to get them to stand so still and look at you either. Nice natural colors and an over-all super job!
This is a wonderful picture of the horse, nice cropping, great DOF, nice textures and rich colors - classic horse ranch feel. The one thing that bugs me is the tree in the background - it's a little distracting. I would have either moved a little to the right to angle the tree out of the shot, or would have had cloned it out of the picture. I'm not big on post-processing, so moving to an angle without the tree would have been my course of action. Other than that, awesome picture!!
