I'm interested to see what shape you decided to go with. Did you chop off that tall branch? or decided to keep it? If the latter, I think it's kinda skinny with that height. I would probably keep this plant in the large pot or in the ground to train and grow the trunk out thicker. Or get rid of the tall branch and repot this tree in a small shallow pot giving it a larger impression. Just my thoughts... I'm still learning like you.
