Welcome!
Healthy tree, congrats.
As a literate will not need taper, maybe you can pull this out.
All branches have to go and some really heavy bending of the main trunk, with raffia, will be needed.
Literatti seems to be an easy way to style a leggy tree, but in fact is one of the most difficult; it has to show a tree struggling against the elements, old bark, sharp bends et all. Difficult but not impossible!
