alright kids, today we're going to practice drawing from a model. julie, could you take off your clothes and pose on this stool in the middle of the class?
what?! no!
julie, your grade is depending on this. if you don't do it i'll have no choice but to fail you.
umm, but... well... okay.
anyways, as i was saying today we're going to be drawing from a model. please draw this chessboard. pay close attention to your use of perspective.
