I love the flatwork pics. There's a few where you lower leg looks squinched up, but I think that's because your stirrups are at jumping length which doesn't allow the leg to stretch down that much. Great job of straight line from elbow to bit. Maybe open your shoulders a little and try to relax your upper body a little more. Looks a tad stiff.
Jumping pics look okay. You've lost your lower leg in a few of them as evidenced by your seat being ahead of the pommel over the fences. Lots of trotting half seat should tighten that up quickly enough. Your upper body is a litte more forward than it needs to be. You could be a little more upright without falling behind the motion which would free your horse's shoulders up to jump. A little more release.
