I think you look great, the both of you look wonderful - good for you :)
Your leg is ABSOLUTELY FABULOUS! And your heels are doing their job, and I love your hip angle, strait back and looking forward - buuuut there is something amis here....you didn't allow your handsom man to lift you out of your tack.
See how your crotch is over the pommel of your saddle, and see how much space is between your seat and your saddle - clear sign of jumping ahead.
But that's ok - it'll come. In compareson to where you were before - I'd say much better!
What I see happening, is a combination of 2 things. 1) Anticipating the fence 2) Not sinking into your lower leg and heel/bracing with knee's to lift you out of your tack.
So - lets work on those two things.
First thing is first - open those knees and sink down into your tack. Do something for me!!!!
Stand up, put your feet shoulder length apart and sink down into your knees. While you do that, push your seat out backwards. Hold your hands as though you are doing a crest release.
NOW have someone give you a shove - if you loose your balance, you are not sunk down and back enough. IF you do not budge, THAT is where you want to be when you go over a fence.
You cannot do that, if you are gripping your knees. Open them up.
The other thing to work on - stop focusing on the fence infront of you, and start focusing on your horse under you. Rhythm, rhythm, rhythm. Learn to feel your horses movement under you. Learn to rely on that rhythm - ba dum, ba dum, ba dum and just be there.
Focus on where you are in the saddle, supporting your horse to that fence and just allowing it to come naturally.
You know that fence is there. Your poneh knows that fence is there - so stop focusing on it.
Focus on the most improtant factor - your horse, and your rhythm.
Hope that helps!
