Animation Brief - Character Development

The first fairytale that I'm working on for the animation brief is the "Itsy Bitsy Spider" classic. This is a very well known nursery rhyme and it is quite interesting and I immediately had some ideas for it, so that's why i chose it very quickly. The protagonist is obviously a spider, so I started making some rough character development for him (or her). Im trying to keep the style simple and cartoony but detailed enough to give the character a range of possible emotions and situations to get involved in. The tale is, after all, one of sorrow and joy; hardships and triumphs. again, needs to be scanned.
