The Drac picture is not an ink drawing or pencil sketch, it is "supposed" to be a wood cut. (I say "supposed" to be, because I doubt they had the time or inclination to make a real woodcut for the movie.) Wood cuts were the most common way of reproducing a picture back years and years ago. To make a wood cut, the negative version is drawn on a plank of wood, the white areas are cut away with a chisel, leaving only the black areas. This is then wiped down with ink and a piece of paper is pressed onto it. Pulling away the paper leaves a positive version of the wood cut drawing... just like a gigantic rubber stamp!
The best way to simulate it would be using ink, not pencil, and a brush... which, if you are not practiced, is a pain to use! It would be difficult to get the wood grain effect that wood cuts usually have, however.
To be honest, though, this has given me some inspiration... I have a complete set of woodcut tools and used to do woodcuts and wood engravings (same principle, but much smaller and much finer detail) up till a few years ago. I may just tackle this one! It is a wonderfully scary piece! Gimme a day or two to think about it.
