The Killer

Hey guys, I was just thinking a bit more about costume and horror and all that jazz, and it's not really whole-post-worthy, but d'you think it would be a good idea to have the killer wearing some kind of mask to make it a bit more horror? I dunno it doesn't necessarily have to be a scary mask though... je ne sais pas, but then it would be easier to not show it's a girl straight away? Thoughts?
