Totally not relevant to your questions for critique, but I love that she's shoeless. Do you know if she was raced? I'm about to pull my TB's shoes for the first time and am nervous as heck about it, so it would be nice to see one that made the transition successfully.
As for the critique, the only thing I see is her front legs are well under her center. Not sure it that affects anything or not. It obviously doesn't hurt her canter. That looks fantastic. Bet she's great at dressage.
You just have to see your distance...you don't have to like it.
