This is one of a series of drawing I did for a Drawing class this past fall of 2015. As a new student i struggled with texture at first, but as i was going through the different studies, composition and different techniques I started to find it easier each time I did a new one. I liked the most using pencil. I used regular pencil to this cow skull, from 2h to 6b forming shadow and trying to do the illusion of depth.
