I find there is something really satisfying about making a quick Disney Doodle.  When you do this you come to realise that the creative minds behind each of these were not only great artists in their own right but also master technicians as they had to create characters that not only were able to portray the emotions demanded by the movie but also had to be very easy to draw.  In the days before computer aided animation every frame had to be drawn and coloured by hand and so to ensure that they moved smoothly the drawing had to be very simple.  They really did master the ability to emote with an economy of mark making.
