You are a really cute pair. It looks like she is building up some muscle. I remember your older thread, and your challenges with your leg being unable to bend , due to the injury. How brave of you to work back through those scary memory places.
I realize you did not ask fro a critique, and all in all I think your seat is good, just to remind you to not try to bring her head down by locking your elbows and forcing your hands downward. You'd be amazed that you can actually influence a horse that is going star gazing to bring the head down by actually lifting your hands along with their mouth and asking them to break at the poll by a light tickling of one hand, and then giving a big release when they do lower. They might try a variety of different things, like go higher, go right go left, but eventually, the will lower. When you bring your hands down to try and bring them down, it only pulls harder down on the bars of the mouth and can encourage more bracing.
But, forgive me, my small little point got out of hand. As I said, you look nice together and you have what looks like a pretty good seat on a darling horse.
