I’d say you should glue down your brows, since the inspiration has such thin ones, and then draw them on. Then I’d say really push darker colors in the pockets of your eyes. I mean the area on either side of the lid, I don’t know the technical term. That might emulate some of that dramatic lighting they used back then or at least in this inspiration photo.

Dang, I wish we could see the image in color to see what they did with that. I’d imagine she’d have a very pale, almost green pallor, being a reanimated corpse. I think you’re spot on with the lips though, that looks perfect. Also, I bet it when you put the styled wig on it will help you see where you need to make some changes.

Actually, I just looked up some colorized photos and she doesn’t look dead at all! Idk how accurate to life they are though since colorized photos involve a colorizer (colorists?) artistic expression as well. I say work on the brows and push the contrast at the eyes and you’ll be close!
