The horse looks more relaxed with less rushing about in the second video. But.. while the rhythm and relaxation has improved, the horse is still unsteady in the contact and is not coming through, from back to front, and using her back. Probably not the easiest thing in the world, however, for a horse of that breeding and build. The horse is also still young. In the land most of us inhabit, however, the horse is doing perfectly well for a five year old. If you can get your youngster feeling relaxed moving forward steadily, not rushing around like a maniac, you have something to build on.
