In the picture, to much slack there in the reins. But in the video I may notice why :(, she does not respect that bit at all. After the first jump it look like she was about to pull the reins right out of your hands? Also toed out a lot, your heals were good and down but your feet were pointed out to much. As well, you had her on the right lead the entire time, is she sloppy on the left lead? Or maybe you just like jumping her threw the course on a single lead. When I warm up over jumps, I do lead changes as much as I can. The horse has to keep focused and attracted to his job. Plus I think lead changes during a warm up are key for balance. But other than that she jumped very clean and smooth. Threw the video you had good hand positions over the jumps, correct pattern trot and canter. Plus she had no refusal, accept the nose/head issues which I don't like in a hunter
. Pretty horse. Good luck on selling her :).
