This is my neighbor. I drew him from many photos. This is just one.
This is my first attept. As you can see, I was trying to simplify and generalize, turning him into a machine or something. Even though I wasn't satisfied with this drawing, I think it captured the gist of his personality.
This drawing I was more happy with. It includes very little generalizing and just pulls on those features which need be exzaggerated. The ear is generalized a lot though.
