Welcome aboard!
Seems you already have a mother/daughter sort of thing going on naturally. I would lean into it.
That's the main, larger tree, with a secondary smaller trunk (in some cases it's actually a separate tree) coming from the same base. Each can be done in different, but complimentary styles.
Piece of advice from the forum regulars: adding a general location and growing zone to your profile will help us know your climate better, which makes a big difference in what you do when with your tree.
