Here's one more from the wulfen series. Just like the previous versions, I used a very limited set of colors. Greens and purples were very very prominent, as well as burnt sienna.
Since green and purple make a very nice gray, that is handy for metals and fur alike!
Tossing in some lighter colors or dark blue, etc., alters this mix to widen the range of grays. Mixing the lighter gray with the sienna helps to create a grayed down flesh color. Using this tone helped to make the 'fur' have hints of a skin color.
