First of all, I"ll point out the good things about your ride. Your horse is adorable, and he looks like an enthusiastic jumper. You have a nice release and your heels stay down most of the time. Now for some of the minor issues I see: your leg tends to lip backwards over the fence. To try to combat this, really think about sinking own into your heels and keeping your toes pointed forward. That will help you stay balanced. I would shorten your stirrups a hole too- that could help. Try to ride with a bit of a shorter rein, so you stay in a elasticized contact with the horse's mouth over the fence. There are two more things I notice that have already been pointed out: looking down at the fence and laying on your horse's neck. Keeping your head and eyes up and looking at your next fence (not the current one) will help you stay balanced and with the horse's motion. Laying on your horse's neck is a symptom of jumping ahead. Try to stay a bit off your horse's neck, while still keeping a flat back. Otherwise, great job. Good luck to you in the future! Hope I helped.
