Brain Worms

I really don't know what to call this. When asked all I could do was produce a picture of the work in progress. All I can say is that it is a head that is split open to show what is inside. There is no term that can sum that up that I know of. I have put the most hours into this picture that any other project I have made in photoshop that includes the swapping of heads on people's bodies. I had to print it on 4 sheets of paper because it ended up being 13in x 20in.
