I think the reason you have been having difficulty figuring out what to do with it is because you have some major reduction to do. You have strong and interesting pieces on the left and a million tiny seedlings on the right.
I agree with
@Forsoothe! the left is strong and interesting where the right doesn’t have much going for it. Next repotting I would saw the extra rootball off, change the angle dramatically to the right and put it in a much smaller training container. This is very rough, but what I am seeing from the pictures provided.
