Entry for the Musically Inspired Design Contest
The little demon on the bottom right is actually a character I made in 2009. His name is Scratch and he's a DJ, hence why he was perfect for this contest.
I might add more demons to the design later. For now, I really need to get to bed. Got a long day of work ahead.
