Glen, of the trees shown, your first one does it for me. As a bunjin it should have less foliage and branching. Which would do two things...#1 help the image as a bunjin/literati and #2 help with your query about keeping it tidy and manageable.
A quick down and dirty virt which hopefully will get across my thought. Not sure if the bottom right branch is necessary
Anyway nice piece and if it becomes to much pinching drop me a line.... I'll relieve you of that stress
