Yes and Yes! From a detailed perspective for design seeking the best possible form for the material being considered.
1. the trunk line is the key to quality along with nebari.
2. the tree is young and still under development in Bonsai terms, not a finished or designed tree! its of time for development and refinement. With only one section to correct on the trunk line. it already has a very nice lower portion or in other words a great start.
3. desirable trunk characteristics for informal upright include a combination of movement and taper. This combination should display shorter internodes and progressive taper as the trunk develops from bottom to top. Each progressive section from bottom to top should be shorter in length and progressive in taper while continuing the movement beginning at the base. So id the base has gentle turns that should continue further up!
if you choose to develop the left side you are keeping a longer straight section with little or no taper beside a base that has nice curve and taper in the beginning. Also the second section above the lower right branch is a longer internode ( section) than the one below the first branch even though it is the same width. This actual creates visually a much loner and more obvious straight section for the trunk line. Not desirable!
Many would be satisfied with and happier to have less work to do and a shorter time frame to get to a more finished look on the bench! Not everyone works toward developing higher quality trees. However, you did ask for advice and I feel you should understand what you are giving up in terms of quality if you keep the left and change the angle of the lower right branch.
It is hard to point out possibilities without expressing judgement. I am comfortable with whatever you decide for your tree.
thanks for considering my comments.
