Charcoal portrait drawing of a bearded man

Drawing a portrait of a man by starting with vine charcoal and building up high contrast with compressed charcoal and a putty eraser.
About Charcoal Flow: These drawings are quick charcoal portraits. I sketch expressively in 30 minutes or less with no planning, just going with the flow. Why? To work on my quick observation skills. My aim is not to achieve perfect lines or flawless shading, instead I try to capture an accurate likeness of the person I'm drawing. Thanks for watching!
