very good shot of the horse, i think it would be a little more interesting if the horse was heading towards the camera, or if the background was a little more interesting - 6
I think I would have liked this image better if the horse and rider were coming toward us rather than riding away. That being said it is still a good photo nice and clear and in focus, good color and composition too!
This would have been so much better if the person would have looked to the right or at least in the same direction as the horse. Otherwise not bad, good use of light. Good luck.
