This weeks Illustration Friday topic is SINK. I first thought of quicksand and Mafia hits with concrete shoes then sinks full of water....then synchronised swimmers...then Synchronised Sink Swimmers. I originally wanted to draw the four characters shown as if from an aerial view as they swam in the sink but drew this to establish the swimming team first. I opted for a Frog as the fourth member over a spider that seemed too similar to the cockroach design. It does bug me a bit that having a frog on the team might be considered cheating if Sink Swimming ever gets into the Olympics though.
