More sketchy goodness

Best bud John Hartwell has taken up the challenge and agreed to try doing up a Sketch of the Week every Friday. You can find his artistic postings on Facebook right here every Friday. John has illustrated numerous RPG books for the likes of Iron Crown Enterprises, HERO Games, Steve Jackson Games, and more. He's a righteous rock-and-roll illustrating stud, so show him some lovin'.

He's also posted a challenge:

(Hint, his dastardly plans were foiled by a certain foursome who are, quite frankly, fantastic.)
