Sorry, I can't see very much at that distance. Looks like you are more secure on this horse. Maybe he give you more energy to post off of?
Only advice I can give is to keep your elbows in to the body. Really engage your core muscles, and bringing the elbows in will help bring you back to your body's center and help with balance. Your elbows out might be excacerabated by hands rolling over with piano hands, but I cannot tell if that is happening or not. YOu sit up very nicely and look like you're having fun.
I would talk to your coach about putting you in a saddle that properly fits you, and the horse. There's not much you can accomplish with position and stabalization in your tack, when you are in a saddle that is all wrong for you.
I think the rear of the saddle needs to be raised up a lot, it is much lower than the pommel - which in turn has caused your body to be placed in the back end of the saddle, instead of the front end.
Aside from that, I think you are doing pretty darn good for beginning, and for the saddle you've been placed in.
Thanks! Yeah, we can only do that circle in the back because it was more open. And, I used to have piano hands, but there not bad anymore. Sometimes they tend to move back though. And yes, Bruski is a German Sheppard, so he doesn't like when he can't see people, even though he knows I was there. But, he doesn't get in the way. =)
Oh, my trainer raised up the pommel because usually the saddle on him comes done a lot, but it didn't that day. We didn't know why. Also, the saddle I believe is a 15, but a 14 is to small, and they don't have a 14 1/2. So, I like the 15 better then the 14... But thanks!
