As an artist, I must constantly up the anti for myself, lest I get bored. At one time, I was thrilled just to be able to make a pleasing face. As I worked, I looked for pleasing faces to copy, and I found that my sculptures were starting to resemble the photos I was copying

Could i build a recognizable portrait of a famous person? How about Shel Silverstein?

Then came a real challenge: Frederick Douglas.
