The picture is a small, dark, and difficult to see, but from what I can see I think you two look great together! The only thing I can really see about your position is that you're looking up, which is good ;)
She looks pretty good. It is hard to determine a horse's true jumping style over a smaller fence, but she has no dangling legs which is a good sign. She does seem like she got pretty close to the jump or had a chip, but she looks as though it doesnt effect her too much and she is able to recover. I can't quite see your position so I wont try to critique it.
