My personal preferences are pretty much corner of the eye or under the lip, which are the vanilla choices. But I guess nape is an interesting one.
Mostly thinking about this because I remembered a character I've seen where the artist decided to give her three different beauty marks, making me think "That's a bit excessive, innit?"
I don't think it's excessive. Beauty marks are just moles really. Not everyone is all clean canvas look like in movies/animes/certain celebs/etc. I think you can have three beauty marks and it'll still look like a regular mole depending how it looks. In that case moles happen lot on everyone.
Well, that is a fair point. Though, looking at a designed character with three beauty marks in three prime estate locations (left corner of the eye, under left corner of the mouth, inner cleavage on the right side), I can't help but feel that's a bit excessive, but might just be my sensibilities...
