I only notices 2 issues, but your basic position is VERY nice.
#1 - Toes are out. Currently this is OK (this horse during these pictures) but if you were wearing spurs you would inadvertantly be gigging the horse with spurs every time you turned out your toes.
Now in jumping some turnout is acceptable (and several pictures show an acceptable turnout) but in a few it almost appears that the toes are turned out so far that the back of your calk (rather than the side of your calf) is on the horse.
#2 - Creast release. The pictures indicate an advanced rider - so time to modify the creast release to the George Morris "middle of the neck" release. Just a more advanced style, for which you appear ready.
Overall a very nice style.
