homework 1: The upside down drawing

Taking a short drawing class in Armory and as a part of it we get some home work to do. The first one was to draw a portrait whilst the original is upside down! An interesting exercise, because the face doesn't make sense when it is upside down, so the goal is just to see the lines and shades unobstructed by the previous knowledge of the subject, i.e. free your mind :)
