Love the name for you horse
1: You want the weight to sink into your heels, you don't want it to be shoved down. You have a very nice bent heel, but it almost looks like you are bracing against your stirrup and your leg has slipped forward a little because of it.
2: Has your saddle slipped? Be wary of getting on from the ground if you are, it can pull your horses back and put unnecessary strain on it. If you don't have a mounting block use a bucket, that's what I use. Relax. It looks like you are starting to sit a little on your crotch and you are hollowing your back. Relax, and sit tall. Toes in.
3: Love the sunglasses 8) . Elbows to your sit and hands down. Just because you are going over a pole doesn't mean you need to lift your hands. Close your fingers and maintain your position. Your horse looks so flashy by the way with the two matching socks on the back and the lovely color.
4: You look balanced, but your saddle seems a little off (centered wise). You have even shoulders and hands. Keep your thumbs up. Your one heel is starting to come up and your toes go out. No stirrup work will help to strengthen your leg position so you can keep it in place better
5: Same thing as 4, except you are doing something different with your hands. Try to keep them even.
6: Move your hands in a little closer together and close your fingers.
7: Your heel is down, but your have shoved your leg forward. You want to try to maintain a straight line from your heel to your hip. You have a nice seat though and you sit very well. Still try to keep your hands even. Even though in a couple pictures I have said this, you have kept your hands really soft which is great, you don't hang on your horses mouth.
8: Your leg looks a little better in this one, but I would still like to see it back a little more. Sit up tall and keep your hands even.
9: Same thing that I have been saying. Except here you need to lower your hand a little and keep them even. You have dropped your outside one and raised your inside one, so really try to maintain keeping them even.
