Here are some sketches from a figure drawing workshop I attended last week. My illustration style is rooted in realism, and sketching from life helps me keep a fresh perspective. The human body is so complex it's mind-boggling, and working from a model is humbling. The more I observe and sketch from life the truer my illustrations will be... Well, that's my theory.
Sometimes the model assumes a pose that leaves me with nothing but a head of hair to draw. When this happens I turn my attention to the other artists in the room. FYI: The gent in the hat is actually drawing with a Wacom tablet and a laptop!
