Done in Photoshop. The main light source is the guy's torch, held off screen. The initial inspiration for the piece came from my spiteful musings about dungeon crawling adventurers and how it's not always all fun and games.
All critiques/comments appreciated.
"Hearing a noise down the hall the brave adventurer sweeps over his torch and looks back for a split second. Just as his gaze drifts, this little prankster pops out of a hole in the wall to dispatch our unsuspecting hero."
