Ha! That the arms still look pewter, that's what's messing with my head here!
I think I can combine these arms suggestions with some others.
First a black wash, just to darken the lines. Then blue and/or purple wash. (On top of the metallic color, should look very nice.) Dry brush on a bit of Chainmal, Mithril and white.
Has anyone here combined white and the metallic colors, and can tell me if that works? I was thinking about that to highlight.
I don't have blue wash yet, but after checking it out online, it'll be a homecoming. Should have had that a long time ago. Wednesday night, hold the register open for $3.70+tax!
