Thanks for the update.
Maybe is better to wait with the repoting until the summer, when the tree will be actively growing.
Until then, as much sun as possible.
I don't know what plans you have for the design, but in the pictures I see several branches growing to the inside. When the tree will be in full foliage they won't receive enough sun and will be weak, more of a burden to the tree, not an asset. Maybe you can cut them now, before they aill be bigger and leave a bigger scar on the trunk?
