Idea for animation

We have been given the task of creating a 15-30 second animation which represents a particular theme or method of animation that we have a particular interest in. I have a massive love for character design, so I would really like to go back through my sketch book and create an animation based on a particular character I produced a while ago.

This is drawing I produced a couple of years ago and I have always wanted to develop it further. I recently used one of my friends as a model and turned her into a real life version of this character. This was really fun because I used paint to create the optical illusion of her mouth gaping as far down as her shoulders. I have designed a lo of characters, but this is the one I am the most desperate to animate at this point in time!
