Last weekend I was at a hospital and was waiting for sometime in the atrium of the building. I had a lot of time to kill. The building had a lot of different people - each one very much different than other. It was great to observe them. I wished I had a sketchpad and a pencil/pen. Luckily I had the iPod with the newly discovered (for me) Sketchbook App ! I went crazy drawing people around.
All of them are quick sketches, taking roughly 1 minute each.
Will be doing more of these and more often I hope :)
