Thanks Allison! Awesome critique! I have been working on my leg a lot since this show and I think it's getting better but still working on it everyday! I've been working on more of an automatic release too so that should help as well! Hunter jumper that is not creepy at all! That's awesome! Who do you ride with? Posted via Mobile Device
First off, your horse is a lovely little jumper. I love his forward pricked ears and willing expression. What a handy little guy!
As others have noted, your primary issue is pinching at the knee, therefore losing contact with your lower leg and pitching your torso over jumps. If you focus on riding with a long, tight calf (no stirrup work in a regular jump saddle over crossrails will help immensely), a lot of these problems will lessen and/or resolve.
You are over jumping for the size of these rails. You look a bit like an Olympic show jumper (in terms of upper body position). Focus on correct leg position and keeping your shoulders and back straight (think "tits out") as you approach a jump (be sure to keep your hips soft, though, so you can easily follow the natural arc of the jump rather than throwing or hinging your upper body over the fence). You really shouldn't have to do a ton of work going over a jump of this size...the horse has to do the work and your main job is to allow him to do it. In a couple pictures you look like you might be getting a tad ahead of him. Be patient and try not to anticipate the jump. Rather, allow your body to follow the horse's motion and keep your eyes ahead (preventing your front focusing too much on the current jump).
Lovely pair. A word of caution, though: if the leg issues are not resolved, you may either find your horse stopping (as you move up the levels) or you will find that future horses (ones less honest or game than he) will stop with you. I only say these things from experience, as I have battled the exact same issues. This is totally fixable and you have a bright jumping future!
