Do you think all/most vampires react to blood the same way, or that their taste for it varies? I know Varney dislikes the taste of blood in canon, but I don't know if that's common in other stories. The vampire women in Dracula lick their lips and act like they're about to feast well, which might mean they like it (and probably another metaphor for scary sexual appetite). OH I think Clarimonde shows a liking for blood, yet guilt about having to take it (or at least her lover's).
On a related note, do you incorporate the drafted inability to appear accurately in paintings, or appearing corpse-like or blackened in photos?
I absolutely hold that preference for blood varies depending on both the vampire and the victim, but evidence for vampire taste preferences is scant in the literature; not only is the actual physical act of blood drinking seldom given much importance in these stories, but a surprising number of vampires don't seem to need actual blood at all. (This makes a certain amount of sense: blood is just a stand-in for life force, and different vampires have other ways of getting at it.)
I love the idea of vampires looking fucked up in depictions, but it's definitely not a trait common to all vampires. For one, this trait in Stoker's lore is linked to his vampires not having reflections or casting shadows, and multiple vampires in other stories are explicitly mentioned as having one or the other (Alinska and Clarimonde definitely have normal reflections, and Liatoukine definitely casts a shadow). I think Kostaki and the boys should get to appear fucked up on camera, though, as a treat.
