This tree is really plucked, so right now, you should just let it rest and see if it’s still alive in the spring.
It would be incongruous to have an arrow-straight trunk culminating in a weird loop at the top. A good tip is to take advice from someone who styles trees you admire, because yours will start to look like theirs over time. If you like the loop, that‘s you’re decision, but the guy started by saying he doesn’t know anything about JBP styles and ended with a “poor example”.
Here is what I would do...since it has a long straight trunk, it is best to work with that feature, and style it into something a bit taller and slender.
Not now, but next spring. Remove the too-low and too-heavy branches (1 may be too heavy too), and then wire branches 2-4 outward, 2 to the left, 3 to the right, 4 to the back, 5 to the right, 6 up, and turning the tips up slightly toward the sun. Remove the rest at the red cut line.
