I was looking back through your art, and I had to ask, as she reminds me very much of someone, and I can't quite place who, but if you could choose a voiceclaim/headcanon for Edith Duff, who do you think it would be?
honestly, i'm not at all sure! i'm not big on celebs/voice actors, so i wouldn't even know where to start thinking about a voiceclaim or anything like that.
i didn't really base her on anyone in particular, either. her overall aesthetic was kinda loosely based on 80's/90's fashion and tech, so if anything i might have lifted some of her features from photos of female programmers or filmmakers from that era? though her plastic murder suit was very much inspired by Hannibal (the tv show), and the undies underneath might have originally been sparked by Ripley's in Alien.
i did once have someone ask me in the comments of one of her drawings if she was supposed to be fanart of Aileen Wuornos??? who she was no way inspired by in either looks or character traits, but i suppose you could draw a comparison given that they're both thin, blonde-ish female serial killers. to my knowledge, though, Aileen never killed anyone with an axe while wearing a plastic jumpsuit, and i don't think she ever wore glasses.
