HAHA!! Never say never!
You are making a great start. I especially like the WHOOP at the end. You did very well. If I were to offer any suggestions, I would say you are grabbing a bit with your knees. As a result, your lower leg is pivoting on the knee and swinging back and forth, especially at the canter. When the leg goes back, it unbalances the upper body allowing it to topple forward.
Let go with the knee and wrap those legs around the horse. Keep more contact with the inside of your lower leg. This will help steady it and keep it in place at the girth.
This is the MOST common thing jumping riders do. Heck, I even do it now and then. Don't believe me? Check my photos. They don't lie..LOL!!
