For this tree to become a nice bonasi you will have to be more drastic in pruning it back. If you look at the trunk you see that everything "interesting" happens in the first 2 creditcards of height. Above that, it if really just a bunch of straight sticks. If this were mine, I would cut it at that height, a little over 2 cards high.
This will get you lower buds, which will become branches. As they grow, gently wire a friendly curve in them, then just let them grow. Learn how to clean up big cuts and prepare them for healing. Mind you, with cherrie this takes time (I have been woking on similar height, similar cuts, for about 3 years and am not halfway through closing the cuts).
The new branches you just let grow this year. Cut back in fall to very short stumps and do the same next year and so on. Slowly you will build a nice canopy. The annual cuts will close over the next season. In some 5 years you can have a tree with pretty much all cuts nearly closed ready for refinement in a pot. (Or do the growing in apot, which is what I am doing)
