The main thing is...you have no energy..she seems like she is sleeping through the whole course. You need to wake her up and get her enthused about jumping.
As for you, you need to do a lot of 2-point work. You are very loose in the tack. You are also relying too much on your upper body to stay balanced. Your heals are up, and your legs are all over the place. Your upper body and lower body need to be independent of each other. If you jumped those jumps with no hands you would topple over. You are also jumping ahead and not getting correct spots. I think that has to do with you being too loose.
You should be practicing your 2-point every single time you get on a horse also try not to balance on the horses neck while your in your 2-point. Do your 2-point at all three gaits. That way you will become more secure in the tack and you won't have to rely on your upper body to keep you balanced.
Your horse is a very willing jumper, and she has a nice form. Good luck!
