my thoughts
While I have barely two months of experience working with
potential bonsai, I'll like to offer my thoughts:
I actually like the side that you have made the back side as the preferred front of the tree. the callous in the front, I think, gives it character.
Also, I think now might be the time to think about the
movement of your tree. The main trunk has some movement that you might want to work with as you develop it's shape. viewing it from your preferred front, it sort of curves left, and then, with the new apex that you're developing there, back right. My thought is that you might want to emphasize that leftward arch (which might require removing that new top branch that you've got there and developing another that moves leftward), something like this (except in these drawings the curve is right because we're seeing it from the opposite side):
Anyway, just an idea.
Also, have you defoliated it yet? If not, you might want to consider doing that in mid-summer to decrease leaf size.
