The Collector

This is my entry for this month's 2D challenge over at the Gnomon Workshop forum. The topic was "The Collector." I've been itching to draw a fighting robot, and with the topic, I thought it could be cool to have a robot who collects the aerials from his defeated foes, as a kind of kill trophy. As you can see by the tally marks on his chest, he's almost up to his 20th victory now.
