Look up! Don't forget the Murphy's Law of jumping. "Look down = fall down". Once you're in the air, the jump is over. Look where you are going next, not at the fence you're jumping. Lower leg looks pretty good. You're seat is behind the pommel which is great. You're not jumping ahead exactly (or your seat would be in front of the pommel) but just try to keep your upper body more upright. You're inclined a little too far forward.
