I don't think you want to go cascade with this, given the detail you put into the opposite branch in that whorl,
yet the 1st left branch is cascading...
It is possible, that the thought process, was to lower the exterior portion of the branch
allowing light to get into the interior, and remove the exterior portion of the branch at a later time
condensing the branch. That is fine, to perform removal slowly in stages. A safe approach.
The wire on the main trunk is not holding anything, and will not change any angle of the trunk if you remove it.
Look at the branch you have cascading. The wire is coiled properly (~60º).
The opposite branch about 45º.
Now compare these to the trunks wire. That wire is pretty much horizontal and has no holding power
which when you think that it does...you will over work the wood trying to bend or hold the bend
but it cannot hold.
The jin up top, is dangerously placed and sharp. It is an eye poker as it is.
Look at the 4 branches in the 1st whorl. Which of the 4 has foliage most close to the trunk?
That may be your bonsai tree eventually.
Beautiful colour. I would not do anything else this year.
Next Fall I would rewire after removing a couple more branches.
Leave a stub when you do remove a branch so healing is concentrated to a smaller area.
Then as the rest dies back, you can get more flush.
Don't forget, JWP are not good at back budding, so they get more and more leggy if you remove
interior growth on a branch. Remove growth from the terminal end leaving enough foliage to feed the branch.
This means buds should be visible further back and left to grow.
If you remove from the exterior, with no other terminal end with buds further back, then chances are
the branch will die.

Where are you? Hopefully not above zone 7 for WP
