Your horse is BEAUTIFUL! Lol.You look really good. The only things I would say are to make sure your not infront of his/her motion, or "jumping ahead". Also try to keep a more steady connection over the jumps. But you guys look rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrreeeeeeeeeeeeeee eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaallllllllllllllllllllllllllllll lllllllllllllyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy good
I think you look very good! Your leg is strong and not sliding back, and your release is very nice. It's been mensioned already, but I think the only problem is the jumping ahead. You are coming out of your seat a little, which I have a habit of as well. What I did was drop my stirrups so I wouldn't be pushing myself up with them. Good luck, and beautiful horse!
It really comes from not anticipating your horse. It's my biggest problem as well, and I think it originates from being so afraid to bump your horses back (as we're schooled is a huge no-no) that we jump out of the tack way to soon. Approaching a jump you should be seated quite firmly in a "driving" motion and then wait for your horse to jump and follow with him.
