The program "Poser" was originally designed by some guy who was using it for his paper art. He would render a figure and then draw or paint it or something. It was easier than having a live model.

You could do the same thing with you pencil art :)  Render the figure as you want her/him and then print it off and draw from that.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
