Chewing up paper

My drawing method is a bit abusive on the paper. This picture shows areas of chewed up paper where the pen went over the same point dozens of times. It also shows a peek at my experimentation with pencils.

This paper didn't make the cut. After the pen went over the same spot dozens of times it gave out.
