Carbon drawing was done in studio on Stonehedge paper.  

This lady was a ballerina for the Canadian National Ballet.  I swear I've never seen such a muscular torso on a woman in my life!  Never mind a six pack this was more like a twelve pack!  It was very interesting and challenging because she has muscles and curves in places that did not seem normal to my eyes therefore I was always second guessing my drawing.
