We loved seeing this step-by-step portrait drawn in only ball point pen. It's an article at Empty Easel that takes you through the complete process, even telling you what colored ball point pens to use to create a realistic skin tone. Does it seem unbelievable that it's ball point pen? I guess you have to try it to actually know it's true. Obviously, you'll need a lot of patience and a gentle touch to create a photorealistic portrait like the one in the article that you see below.
