This is a piece i of a family of gorilla at Asheboro Zoo. It was amazing how they came and set down like they did. My wife took a picture of this and i drawed it. I changed the surroundings to make them look my free. On this piece i used Drewent graphite pencils on 400 series paper. The original is on 18"x24" paper. With the matting and frame its 24"x30"
