I really like these incised accents that you are incorporating into the build. They are unconventional for ship modeling, but so effective because they capture light and shadow to such good effect.
It’s probably too late, at this stage of the build, but it made me wonder whether one could design an incised upper bulwark frieze lattice that mimics what you see in the Pierre Vary color portrait:

For all practical purposes, I don’t know how one would go about this unless they had templated a precisely fitted veneer sheet to cover the bulkheads, as opposed to individual plank.
The CNC. seems capable of cutting very fine incised lines so, theoretically, one could also incise plank lines.
Anyway, I thought I’d share the idea.
