Where's your helmet!? Although you may be a very experienced rider, you should always be wearing a helmet while jumping. Accidents happen, and there's no way to prevent them. Please wear a helmet when jumping.
Your center is pressed back, which is a good quality to have in your position. But you are laying on your horse, which often comes with being ahead. With having to balance your weight on a pony, you have to make sure you stay off of her forehand before and over the jump. Also, you have a nice crest release, you're not catching her in the mouth.
However....When you're upper body is independent and not leaning on her for support, you should practice an automatic release (keeping a straight line from her mouth to your hands.)
Also, your toe is turned out but your leg is secure. Make sure though, that your weight is all in your heels for more elasticity on your landing and through the jump process. Locking your leg compromises your position.
distances are like men. never grab the first one you see; it's never the best one, more will come along.
