Last year, about this time, I took my first ever figure drawing class. And I must say it was long overdue. I don't feel that my skills had ever improved so much in the same period of time. I definitely need to do it more often.
For this piece, the model was laying on his back facing away from me, and I didn't feel a full-body sketch was really that interesting. So, rather than move, I punched in on his face and drew that instead. I think this was a 10-15 minute pose.
