First thing, I think you have a really good two point position, Expecially for being bareback
I am not sure if you do but if not you should really take some jumping lessons because you have potential
If you could wok and bringing your horses head down it will also reall help your two point position, You can bring her head down by bring your reins up to your chest and pull a little bit at a time and give her more slack the lower her head gets.
But in all it looks like you two have a really good bond
Best of luck
