Bic Pen Drawing Portrait of Man from Nashville

This is a drawing made with a common office supply pen - the crystal bic pen. I find this pens to be exquisite to work with because you can get so much shading and tone - all with one tip of a crystal bic pen. 

This particular portrait is sourced from a photograph featured in Juxtapoz magazine of a man from Nashville, Tennessee. When I saw his face, and his tattoo of "Fear God" sold me on drawing him.
