Toward the end of last semester I started drawing these little imps at work. With traffic at the bar being generally slow, I filled quite a few sketch pages with little old man trolls, and even developed a loose story relating them to witches and housework. I won't say more because that' about as far as I got, but who knows where they'll pop up again?
(Sorry for the cruddy scans, btw. The scanner I used belonged to the school, and was very worn and torn from a semester's worth of use.)
