I actually think this horse has a nice natural form over the fence I like how she uses her neck and rounds over the fence. She obviously doesnt know her spot yet, since she is either taking a long spot or short spot. Cavalitti, ground pole, and gymnastics will really benefit her. Her knees aren't even in every picture, but she's still green..that's something she can work on. She sure has a lot of potential.
As for you, your best shot is the 5th picture. You have a good leg, and a good release. But in every picture, except for 5, you are jumping way too far ahead. It looks like you actually on the horses neck. Try sitting longer and pushing the horse forward all the way to the jump, then 2-point when her front feet leave the ground. You are jumping for the horse, which later on can result in refusals, if it is not corrected.
I don't know if you are like that because the horse is green and you were concentrating more on going over than anything else, but look at picture 5, you and the horse look the best in this picture. Just try to achieve that every time you ride.
