You are going to need to reduce those low branches to one so you avoid "bar" branches. A lot more growth is needed before you can though. I would just let it grow for a bit to see what develops.
Update!
Two years later, i m not sure yet it needs some buds closer to the trunk
Id like to repot it into a collander this year since it is in not so well draining dirt right now my last year summer repot on my mugo mughus went wel and i learned from that to take less of the roots at one go
Looks like creating that Shari and Jin all in one shot worked out well. Doesn't look like it affected anything above it. I've been letting the stubs, left from branch pruning, dry for now. I'll jin or cut flush in a year or two.
