Great suggestions, everyone. You folks have excellent taste, if I may say so. Keep them coming...

So far I think I've only seen Scarlett Johansson and Isabella Rossellini seconded. It's not really a democracy, but if I see lots of people back one particular suggestion, I might be more inclined to try my hand at that one.

momodot: I'll most likely try and make separate morphs for different parts as you suggested, so that they can be mixed later. It requires a bit more discipline, but I think it's well worth the effort.

PS: Celebrities might not always be the most beautiful or the easiest to find useful references for, but they are the easiest to talk about.
