I attend a life drawing group once a week. As an illustrator and artist I think it is important to continue to develop basic drawing skills. I draw a lot of people in my work. I would be remiss if I did not keep my understanding of the human face/form sharp. First image is from the drawing group. The second image (not derivative from the drawing just an example) is a personal illustration.
I used one the model sketches from our life drawing group to create this image: The Human Machine Interface in a Time of War
