You two look great, as always; I really like you two as a team.
Well, Charli looks like he is maxing out at about that height, so trying not to push it past that would probably be a good idea. On the flat he seems like he is having a hard time with his headset, but im not the right person to talk to about that. ;]
As for you...
Your heel is popping up missy! Really try to work on that. There are things you can do on the ground to help your heels too (I know some...). Your hands/arms look good over the jump, though you could move them down a little on his neck (though it isnt that big of a deal). Maybe try to roll your shoulders back, as you are hunching over pretty bad. Also, it is hard to tell, but it looks like your knee is over your knee roll (like your knee is going infront of your knee roll). Maybe your saddle fit, maybe your stirrup length, I dunno. "/
Great as always. Take what I say lightly, as I am not nearly as good as you, but that is just my two cents! ;]
You can never take a Thoroughbred away from a horse crazy girl.
