way too cute...a different crop of the photo might have made it more appealing...maybe a little more forground or a little more background would have lead your eye to something...but again that's my opinion! 6
While I like the choice of subject you made here, I think that the horse butt is a bit too prominent. I think shifting your position or just waiting for them to move would have greatly improved this shot. Your DOF use is well done and isolates the crisp subject from the blurred background.
