It looks like you are doing 2'. When you are jumping fences around this height, you don't need to come up so forward during takeoff. So look at your picture, look at your hip angle, and imagine yourself closer to a verticle position. The hip stays, but the upper body does not reach so far forward over a jump this size. Over bigger fences you get closer and closer to the withers out of nessessity.
I hope that helps. Over a fence this size you don't need to come so far forward. Remember that we go into this postion based upon Caprilli's findings that you need to keep from inhibiting the horse when it jumps. You only need to go so far forward with your upper body as the jump and horse's jumping style requires. You are definitely not inhibiting your horse here, but it would be in better 'form' to separate your upper body farther from his withers over the fence this size. As you get into higher jumps, imagine you are just coming into that takeoff position to keep from hindering the horse and to communicate the best. Your horse will tuck his knees in much higher and have a more vertical takeoff - so your takeoff position is only slightly changed only of compensate for the bigger jumps. Ohh dear I hope I haven't been confusing. Don't get me wrong, you look GOOD! But for the sake of 'judging' I thought I would point this out for ya. Start thinking about following his mouth with a straight line from elbow to bit - if you practice and are strong enough, it will help communication better than a crest release.
