I went out as an NPC barbarian shaman with a skull painted on his face, with a red band across the eyes. It got some reactions, but I guess it was distinct enough from the usual undead makeup that nobody attacked me on sight. It was well short of the size of my face, and I made sure it had sharply defined lines. I had a few people ask what it was they saw, and I said a guy wearing face paint like this. I think just strolling into town will get you a different reaction than if you're prowling around the woods looking like that.
Would it still serve the character concept if it were more stylized than realistic facial makeup? Instead of making something skull-shaped, a white band of paint across the brow above the eyes, and some white sections below them. You could add some color on the sides of the eyes and the nose -- with some color it's more gypsy-like and also less undead-like. I think red or gold would look pretty cool there. Splash some color (or white) on the chin with some black lines to symbolize teeth, and I think you'd look pretty wicked without being too mistakable for undead.
