If this were my tree, I’d wire it out, and try to set the primary branches and secondary branches so that they will start to develop “pads”. It’s always hard to tell from pictures exactly what is going on, but it seems that branches are going every which way…. I see some sections where the heavy part of a branch is not wired, but it is wired up near the tips, but the wiring “doesn’t make sense” to me as I can’t see how it’s building a pad.
You have to “splay them out” to create a horizontal surface for the pad. This allows the sunlight to pierce into the interior and will help the tree to backbud new twigs closer to the trunk.
Since you didn’t decandle last summer, you will have to contend with long needles while you are wiring. Just take your time, and try to wrap the branch and avoid trapping any needles. Yes, it’s a pain! After you have set the branch, then you can selectively remove the needles that hang straight down. This will make the tree look tidier. And it will also discourage the tree from making buds on the bottoms of the branch. If it does, you will just have to remove them in the future.
JBP go thru an awkward “ugly duckling” stage where the foliage is long. Once you start decandling, you’ll get shorter needles, and the whole thing starts to resemble a tree rather than a porcupine!
For reference, here are several of my JBP under development. I did decandle them last summer, and i have pulled the old needles, but hopefully you can see how I’ve splayed out the branches using wire.

When wiring JBP, you don’t have to make the tips point up at the end. When the new candles form, they’ll grow up. You can see from my trees all the new shoots that developed after decandling grew straight up.
