I would start black, heavily highlight Dark Angels green, then snot green then glaze with Dark Angels green, and highlight with snot green, then snot green with white. I WOULDN'T drybrush too much, as the face is the focal point of the miniature, and you want that to come out nice every time - I find drybrushing is a little too unforgiving with mould lines and small imperfections..
