Apart from over riding like everybody has said, you look great! Excellent secure lower leg, just rember to let the jumps come to you, and let the horses jump push you into your position :) I have an excellent instructor who explains jumping position over a fence very well.
You know in 2-point position that there is 2 points of contact (your legs which provide the 2 points of contact, and you seat being out of the saddle), and usually you use this poisiton between jumps in XC, and some people use it jumping.
You also know that in 3-point position there is 3 points of contact (leg and seat, usually used between jumps in SJ, and when you need more control), well imagine a mix of the two, we will call this 2 1/2 point position.
So this means over the jump you should quietly fold into 2 1/2 point position, where your seat isnt out of the saddle by miles but enough to allow the horse to move his back :)
Hope this makes sense, and goodluck!!
