is the decision to leave the lowermost right branches purely an aesthetic choice?
Not that I can answer for Brian, but that is an aesthetic placement for which there is a guideline. In general, we want to stagger branches, because "bar-branching" (two branches on exactly the same level leaving the trunk in opposite directions) isn't really as common naturally, and the most basic idea in bonsai is that you want your bonsai to look like a
natural, full-szed tree. Staggering means, of course, that there will always be one lowest branch on one side or the other that is lower than the other side. Also, I think another reason for this guideline's genesis, back when people were starting to develop guidelines for bonsai way back when, is that
uniformity , regardless of whether it exists in nature or not, generally gives a viewer a feeling of human-imposed order and artificial-ness, which is not what we want to relay with our bonsai. That's just a personal opinion - we'd have to ask those aged guideline-makers what they were really thinking to be sure, but, well, they're not around anymore
And Brian - this tree is looking very nice! And the whole display looks nice as well, though I don't know anything about rules for displaying bonsai with accent plants (except everything that Al wrote on Victrina's thread, which I haven't entirely digested yet) so I can't give any kind of a professional opinion, but it looks nice
