FYI, here's the mockup I made for Tom & I to try out ideas. This is not an actual guitar – yet. Just playing around with graphic elements to see what they look like... I've also included the original close-up photo of the rosette.
What I added or replaced in this mockup was the rosette I liked, with ebony sound hole binding, circular fret markers with ebony dot centers on a Brazilian fretboard, and I lightened all the Braz. elements and boosted the saturation slightly since Tom told me the Braz. he'd be using on my guitar is lighter in color than some.
I expect the actual guitar to look similar to this, but we have a long way to go yet.
