Hey David,
Nice little tree you have there.
Is it the Japanese maple variety "Little Princess" by any chance? I happen to be making a video on this variety, and yours looks very much like mine.
I can see you have tried hard to make the wiring sit loose on the branches so there is some space, which is great.
Yes, less is more. Just clipping of the branch however does not tell us where you want to go with the tree. Do you have a final design & size in mind? This will help determine which steps to take now. Note: THe tree as it is, with or without the side-trunk down low, has a pleasing look to it already.
A before and after of my little princess, as example. Note it is planted at a slant, and that I looked for taper in the trunk & branches, as well as movement:
