I really like that tree. Not as good as your plum, but still, I like it a lot.
It does seem a bit instable though. The first branch on the left is imo not heavy enough to counterweigh the crown, but I think it could easily be solved by bending to crown a little back towards the left. If that's possible.
Well @Tentakelaertje, I not only managed to move the crown to the left a bit but also raised the second trunk at the same time. it's about as far as it will go. I already cracked the main branch in the process.
