Here is what I see, he is going all off of his front and he needs to be propelling off of his haunches.
It also looks like he is trying to trot in the back.
His back is also flatening out. You need to round him up more and I think that would also help the haunches issue.
I also noticed that he is backing from his front, I would like to see him backing with more speed, and I want his hip over his hocks, that's when you know there moving from the hip.
Does this make since at all?
