Not really my department being a big tough man and all , but David Bowie's Aladdin Sane/Ziggy Stardust era make up is pretty amazing. More stage make up than actual make up tho.

Or widgets if you can find any images of Siouxie Sioux in the late 70s/early 80s, I think that early goth look is pretty cool. If your looking for inspiration, these kind of extreme, out-there images might help to provoke ideas, even if you have to tone them down! Good luck!
