The thing that jumped out at me the most is that you're trying to sit to your fences but you haven't yet developed a following seat, so your seat looks busy and like you're driving the horse. If you were showing, I'd advise you to ride to your fences in two point, it would make for a better presentation.
I'd also advise that you spend some time on a school horse on a lunge line and really learn to master a quiet, passive following seat. You have the idea and the beginings of one, now you need to solidify it.
I suspect your instructor is having you work without stirrups to address this problem, but even without stirrups you tend to jump up the horse's neck rather than waiting for the horse's motion to push you out of the tack, and then also snap back a little abruptly on landing.
Your overall design of position is excellent, and you appear to be a strong, capable rider. A true following seat, and allowing the horse's motion to open and close your hip angle rather than doing it yourself would add polish and take you to another level.
