This is the page in my sketchbook on which I did my original doodles at the beginning of the Movember project. I was originally going to have a full face in the animation, but I then decided against it, because having the bottom half of the face meant that the moustaches were more of the main focus.
From creating this page, I was able to narrow down my choice of facial hair which would end up being used in the final animated video. The expression on the characters face was going to be part of the animation too. I was going to have it where his facial expressions would change depending on which moustache popped onto his face, but never got round to doing that part of the animation properly.
