Which jumps? Because I am seeing the swinging but to me it looks more like I'm moving my leg behind the girth over the jumps and then back forward afterward. Could you be more specific?[/quote]
Alot of them, it is most obvious in the second time through the cross-rails, the jump that is an x with a vertical, the jump that is infront of someone on a chestnut with a white face (this one you foot is still infront of the girth a few strides after) and the barrels. You leg ends up almost straight with little to no bend in the knee. Its the "skiing" position. Yes you do move you leg behind the girth at the peak of the jump, but that is where is should be throughout. It looks like you don't have a really solid connection with your lower leg. I believe pinching with the knees is one of the causes of the leg swing.
P.S I love the heart clipped in

It is very cute.
