You are speaking of the lower branch to the left (the one I pointed with an arrow), right?
If so: yes, I guess I will still get rid of it and turn it into a little deadwood.
Because my idea originally was that the trunk line was the line I put in green, so this branch was to be removed.
I pruned it last summer and following Vance's advise I kept more than 1" to avoid to kill a part of the tree. Obviously I let too long so as you say the branch is just half-dead
The tip is dead but not the last inch or so.
This summer I think I will pluck the buds and then prune the branch again just at the start of the leaving part removing the dead tip.
Like that I assume that next year the branch will be totally dead.
At least this is the plant, unless the numerous buds all over the place give my new little branches that give my a new idea on the way I would like my tree to evolve.
