Good heels and nice release in the second pic. Head and eyes are looking up and ahead. Very nice. Your leg in the second pic seemed to slip back a tad but not much and maybe your stirrups are a hole or two to long. I say this because you are jumping ahead and doing the work for your horse so when one thing falls short we compensate by doing extra someplace else. Plus your leg just looks real long in the pic. You want the bend to be around 120 degrees.picture it by thinking of a square (that corner is 90) then just picture 30 more degrees. That gives you a good basic idea of how your leg should look. All that being said wen you shorten your stirrup that should greatly help you stay in the saddle better n not feel like you have go jump ahead. Your bum should come wayyy back and just come up (not forward) out of the saddle enough to clear your horses back. As for your back im glad its not arched however you have hollowed it out. I also feel that this will stop wen you stop thrusting forward . Most the errors can be fixed by a tack adjustment so other than that you look real good. Love the first pic. I would frame something like than n put in my living room! In the last jumping pic your knee angle looks much better but its also hard to see because of the dark boots and saddle. But the same issues with the first jumping pic are seen in the last. Your just jumping ahead. Bring that bum back over your saddle n just lift off enough to clear it. The pics of the flat look very nice. Your very straight and a line from hip to heel is straight. Only thing I can say here is rotate your wrists so your thumbs are more to an uprite position. Other than that very nice n your horses are making nice efforts over these jumps. Mostly the first jump pic. He brings his knees up nicely over a small fence.
I like your release and that your looking ahead to where you need to be going next, your upper body is nice.
The first jumping picture looks as if you are jumping ahead which is causing you to lean on your horses neck, wait for your horse to jump to you. In the last jumping picture I think your stirrups are to short (should go down a hole or two) which is causing you to exaggerate your heels being down way to much IMO. Your should use your WHOLE leg as an anchor, not your heels. In the third picture, same thing, use your whole leg, force your toes in to help.
Keep up the good work, you and your pony look like a great match!
Basically all the crit up their I agree with :) you have great release!! I like how your eyes are looking ahead and your head is up! Great job! In the second pic you needed to just stay in the same position but just raised your chest up and brought your shoulders back so you weren't lying on your horses neck as much. Think the other pics are covered so not going to comment on them. Great job and keep up the good work! The ponies are so cute!
