your leg seems to drape down a bit better, though I wish that someday you can find a saddle with a very short flap. your stirrup is just barely short enough for you to work well.
as for some things that you can do to correct your body position, and these are the things we pretty much all work on . . .
don't let your lower back roll forward like that. too much rolling foward puts you in a "weak" position. on top of that, you need to get your elbows back at your sides, so that your upper arm falls as vertical as possible. keep your thumbes on top, on top, , on top! again, allowing the lower arm to roll over , with a flat, horizontal hand position, encourage the elbow to come out, and this is a weak position.
here's a couple of things to help you imagin good hand position. think of your thumbs as being a little "roof" on the top of your bent fingers, which close softly to form the "house" while your thumb, on top , is also bent to form a roof.
the tip of your thumb should point, just like a lazer, at the bit rings. laser, laser laser to that bit, right down from the peak of your thumb roof, out the tips. if the roof tips to the side, it will fall off of the house! keep it on top!
and, when you've got a nice steady contact, with your thumbs up and elbows in, you can give a signal to the hrose by mearly tightening your forearm and kind of "pinching" your elbow, with the firmed forearm muscles, against your side. you dont' need more than that in many cases. try it.
