Looking into human anatomy, specifically the muscles. I drew a few images using different materials and a diagram of the human body (front and back) labelling specific muscle groups.
I attempted to use different effects and materials. The layering of pencil, red pen, black Biro became a little dark. I found using red felt pens to make an interesting layered effect. This looked very convincing as muscles. Although in hindsight i should have went over some of my pencil lines with in in order to stop the pencil lines fading into the background.
