The vampires in my oc verse have sort of like a power-up form where they're much more feral and out of control, hence the name. Not too much is changed about their personal appearance, but for Raven I wanted to give her big paws/claws to make her more crazy looking LOL. Also I've been experimenting with my Sonic style a little to make it a mix of canon anatomy while still maintaining the curvy figures I personally love to draw.
