I can't really judge his price from just a video, but I'll tell you what I see at the lope. To me, he looks artificial. While he is still pretty much 3-beats, look at where his inside hind leg is, especially his hock in relation to his hip. It never really goes up underneath himself, and he gets really far behind. His head set looks forced, like he is being made to keep it there. It needs to be more level, with his face slightly in front of the vertical. The other thing is that he needs more forward momentum. Yes, WP horses are supossed to be slow, but remember that they are now asking for "a lope with forward momentum," and this horse really doesn't have much. Moving him forward a bit, and letting his head come up and out will help with elevating his shoulders, and letting him reach forward with his front leg. I would also work on really controlling his hips, making sure you can push them to the inside, at both the walk and lope. Then spend some time hand-galloping him; it won't ruin him, it will actually help him learn how to correctly use his body. Feel how he drives from behind while extending that lope out, and then when you slow him back down try to keep that same drive from behind. It will take a lot of outside leg to drive him up and to keep him there, but I think he can do it. And it will help him tremendously. He's a cute horse with a lot of potential, and I can see how he would be competitive at open shows, especially since he seems so broke, but his lope won't work at the larger QH shows. With some work I think it can, but not how it is right now. And I'm not trying to be harsh, but it's obvious you've put a lot of time into him, and I want to give you an honest answer, so you can keep on improving with him. Best of luck!!
