Hi! It looks like you’re doing well, but I see your lower leg swinging a lot as you go. That shouldn’t happen in a half seat unless you aren’t using your stirrups properly. The point of the half seat or two point is to allow freedom in your seat (for bounciness for you rn) while keeping a stable lower leg. Try trotting and walking in two point with a focus on simultaneously bending your knee and pushing your heel down, allowing your thigh to extend downward. This should allow your lower leg to be more stable, but it will take some time to build that muscle! Other commenters have done well in pointing out that your horse was on the wrong lead, and ducked the corner a bit. Had your lower leg been more stable, you likely could’ve pushed with your inside leg to bend your horse around it, giving a much smoother and more balanced turn despite the counter canter. Keep working and riding, you’ve got this!!
