From the angle you have shown us the rear trunk is almost completely hidden behind the branches growing from the main trunk.

There is little point in having something that cannot be viewed. Maybe look for an alternative viewing point? (try viewing from the other side so those 2 branches become rear branches) Remove the branches and grow new ones from buds that will sprout on the rear trunk?
Like most developing trees you will probably find that in a year or 2 it will be so completely different that you will need to change the styling anyway so no real need to get hung up on one vision at this stage.
new buds can take 4 weeks, sometimes quicker, sometimes a bit slower.
