I found the shadow to be threatening and scary (that's a compliment, by the way.) Actually, it reminded me very much of the final few moments of "An American Werewolf in London." The overall simplicity of the elements of the image is well thought out for poster art. A strong poster is usually not cluttered. My only constructive criticism is that they young woman's face is a bit dark in the shadows, but perhaps that's the effect you intended. Great work!
