How would you suggest to balance it Auk?
The right side looks OK to me. It is a bit too full, but that is not a problem. Once you start getting ramification you can still decide what to keep and what to remove.
The second branch on the left side is the biggest 'problem'. The part that is growing upwards does not seem to fit in the silhouette of the future tree.
Also it seems to conflict with the other branches growing down.
The first branch on the left seems too long.
Great that you made a video, by the way, it does help. Still, only you can see the real tree, from all sides, so I do not recommend to take my advice but make your own decisions. I will not pretend to know better than you do.
