The text is very hard to read, and it'll be hard to read against anything but a solid light colour. The teeth and eyes in the text feel a little silly and create distracting contrast, hurting legibility further. Maybe have the text be light-coloured, and have a dark shape of the wolf and other creepy things as the background for the text. That will allow the logo to be legible on any background, as well as give you something menacing to work with.
