Batman: Arkham City was short before being released when Patrick Brown  from Australia draw this Illustration of the game while he did not have a lot free time to use. He mentioned he was only spare to work like an hour per day on this but enjoyed every minute of it. Who can blame him? Creating something beautiful for a great game is just pure fun!

The backgrounds in this piece are actually screenshots of the game with an additional blur effect, but the focus is on Batman and his enemies there anyway.
