More Poster Idea's

Once again here are another couple ideas for our poster. However, they are also snapshots from our teaser trailer so the quality of these images are not very good.
We have planned to take pictures using a digital camera to get better resolution images.

We decided to keep the images black and white. But copy and paste the killer standing in different areas of the same shot and reverse them so that the characters looked eerie and suspicious. The audience are left wondering whether there are a high number of killer characters or is it just one.
I don't believe we are using many aspects of these ideas just the black and white aspect of the image.
