Fun info about the illustrations: When I draw with marker I always make the illustration in a sketchbook first because the marker paper isn't really good for pencil lines. So now I have a nice working sketch for not 1 but two illustrations because they are on opposite sides. You will have to make some decisions which side you want to show off.
