Time limit

On the last few classes we were given a short time limit on drawing the models poses. Sometimes the model would stop and do a different pose each time, then he would do an action and stop in the middle of that action for a few seconds. What i found hardest though was when the model didn't stop at all, he would walk round the room and we would have to draw him at three different places and keep going to back to each drawing as he passed the area we were drawing from.
