It's the Grim Reaper from Shadowgate! This one is not a troll, and Death clearly flosses! I'm very glad that I spent a lot of time learning to draw skulls in fifth grade, in a period in which skulls were obviously the coolest thing in the world.
I darkened it with a kind of crappy program I didn't understand, giving it a sort of grainy feel, which I like, because it seems more NES. And it reminds me a little more of Dore etchings, which is always okay by me.
