hmm, I am not sure about the masks yet. The principal question is what they are going to represent, is it just human faces or masks that represent human faces? In that case it would be more disturbing if they are actual and more natural faces that hide the horror beneath. In that respect I would not be a fan of the mask in the middle... (but there are many ways to interpret this monster, and not sure if it is something that should be explainable...)
