Last week I went for a fast food at a Food Shop and one guy served me, he had a face that has contrasts-Silky smooth hair on his head but his beard was coarse and curly. Immediately I knew I'll love to put my graphite and oil base pencil into that.
I asked him and he agreed! I took my time to concentrate on these two opposites.
I have used Pitt Oil base pencil (hard and soft) and a H graphite pencil on a self sanded watercolour paper.
