Well... assuming you still want it to look some what like a gargoyle, you could try painting it as usual, using greys and maybe some brown tones. But once you get finish try using red inks (maybe just water down red paint to avoid shinyness unless thats what you want) and glazes to tone the mini. I\'m not sure how well it would work. I\'ve never tried it myself, and I haven\'t seen it done, but I would guess some one has tried it... You don\'t need to use red either, I just picked it because you already mentioned red... Hope that helped in some way.
