Appeal or Character Personality - Principle 12

Characters in an animation should always have what is called appeal, this doesn't necessarily mean god looking but it means interesting to look at. They also need to be developed in the way they look, this could mean playing with proportions but always keep it simple as you will have to draw these characters over and over. Characters not only need to look appealing but they also have to have an appealing personality so that the audience will be emotionally engaged with them, if your character's personalities are bland and boring, audiences may lose interest. I found a good example of how you can play wit the proportions of characters in order to make them more appealing. Below you can see how each character can be representative of a shape and this makes them much more interesting to look at instead of all being the same shape.
