Nice! If you let the leaders grow it will fatten your trunk. If you cut them back they will ramify to a certain degree. Put it in the ground for faster development or a larger pot. You can still get trunk growth in the pot it is in just not as quickly. People tell me my boughie has a slingshot type of situation going on that I need to address (it is true) but I have been growing this for so long I am not in a hurry to change it. That is something you may look at as well.
