Excellent figures again! I think you've hit the white-grey / grey-white / greyish-white / whitish-grey sweet spot on their uniforms that I'm always searching for. I also like your treatment with the faces very much.
I notice the cartridge boxes are brown - which you're correct about. "Apparently, the cover was brown and bore the royal crest".
But now I'm annoyed with you because I now have to go and repaint all my Frenchmen!
