organisation - lighting used for film poster picture

During the photo shoot for my film poster i used extrinsic lighting on one side of his face to create a show behind the main actor, this show will be manipulated into he shape of a devil almost to show how the darkness symbolized by the shadows is creeping up on him. Here are some previews of the pictures taken. These picture are only draft ideas of what i intend for my film poster put the shadows provides a good idea of the objective i am trying to achieve.
