Why stop at generic vamps and werewolves.
I can only speak for myself but the millions of vampire and werewolf movies have kind of ruined the allure for me personally.
Get original.
One word: Twilight. Ever since
that scene came out, Vampires have been becoming less and less of an object of fear, and more of a sixual/love appeal. Same with werewolves.
I can only hope the vamps in Skyrim have at least some scare appeal to them. A vampire in a dark cave rushing you with fangs extended and a demonic hiss/growl sound would suit me much better. As for being a vampire, I hope there's more than there was in OB.
