Illustration Friday "Shadow"

EDIT: There is an acutal shadow on my artwork that was not drawn on the paper. It runs along the man's neck and the bottom-right corner of the picture frame.

My experience with illustrating "shadow" had a great "Ah-ha!" moment in it. At first, I tried to draw people or objects casting a shadow. I could never get it to look quite right. After a frustrating realization that my I could not, for the life of me draw a good shadow, I thought of a classic moment in movies when you see a wall with a shadow of a person and an arm holding a knife behind them, preparing to kill the unsuspecting victim. So, I set to work at drawing the suspenceful scene. I also clipped a picture of a family out of a magazine and put it on to the paper with a picture frame around it. I did this to contrast the two different planes (in terms of depth).
