I will want to go physically look at the tree and see how far off from that angle (3902) it did get planted. I raised the right side, as that was the intention, (there's a block on the back right of 3902) but looks like the rotation is a bit different than the photo. When I was potting it, this appeared to be the best "front" in person. Yes the branch was brought back up to straight at that point, as I raised that side. I don't know that I will ever be able to lower this branch, and don't know that it's all important to do this. It would be better I think, but don't see that as a terminal flaw? As far as three branches coming from the same spot, that issue was solved with branch removal a year or so ago I think.
I would really like it if you could lay out the structural problems you see with the current angle if possible, and I for my part will take some photos tomorrow with different angles to look at. I did very little rootwork when I moved the tree to the new container, other than raising the back right side, so the angle could be changed again relatively soon.
