looks nice

I do wonder if messing with normal maps would make a mess of it;
if that medallion stuck out or look pushed in just a tiny bit, it might add
to the overall aesthetic of this submission.

It might be just me, however. That said, I have little knowledge of producing textures.
(In retrospect, this idea may not be a great one, as all skins are essentially paint jobs that would wear off.)

Not sure about the cyan/aqua parts, but the rest is lookin' great.
