For this project we had to do an "inside out" picture; basically a picture of something (a face) that had something else "underneath". I decided to do a woman and a skull. I had a hard time finding a skull that had the same or similar proportions to a face. Eventually I found one that matched nicely, especially with the shadow on once side of her face in the actual picture. Now it looks like she is sleeping and in the dark you can see her skull.
