Very good attempt to capture motion with sun as the back-light. I would suggest in the future compose such that the horse is more to the left (if its moving right), to remove some of the negative space and give us an illusion of running room to continue its motion. So if subject is moving left to right, keep it close to the left of the frame - this way the eye will follow its trajectory toward the right of the frame . Of course too much negative space on the right is not good either. At least that's one of the rules I try to follow when shooting objects in motion. Regardless - great photo.
