Surrealistic Theme

The theme for my surrealstic project is along the lines of everybody has a soul mate in a relationship. My models will have their faces morphed into keys, and key holes symbolizing that one key hole has a specific key that goes perfectly with that key hole. The bodies of the models will be seperated at the waist symbolizing that you don't find yourself completely until you meet this other person. I also want the sky to be multicolored and set at a random location just for the surrealistic factor of the assignment. If I can work it out, I want the corners of the picture to be burned or ripped or distorted to show that nothing lasts forever.
