I did this drawing to kill the time on the plane back from Malaga the day flights restarted after the volcano eruption. The guys were occupied with handheld gadget and not really aware that they were being drawn. The light from the windows was very bright and I don't think I really captured that but I was pleased with the sketch particularly since I didn't let myself rub anything out. I didn't really enjoy the flight I kept looking out for plumes of volcanic smoke.
