The rider is obscuring the horse's full abilities with unstable and strong hands. From what I can see, from either fault of the rider and/or the horse's natural ability, he is lacking compulsion and is heavy on the forehand. I am not too happy with what the rider is trying to accomplish frame wise, but put a good rider on him and he may move quite differently. For a jumper, you really do want a clear conformation picture and a video of him actually jumping.
