Waiting Time Wheel-y?

Watercolour pencil in Moleskin sketchbook

Poor old sketch, but it was difficult circumstances - sitting in the car late at night barely able to see and with nothing much to do for 10 mins, so of course I got out the sketchbook. I was surprised that I actually managed to get anything resembling a wheel and I did not actually see the result until I got home. Good way to use up 10 minutes waiting time though!
