When you make a 3D animation, it is ve important to plan it very carefully. One of the most important things amon others, is the charater's expressions. Planning those hels get a general idea n howwe can morph the character from one expression to the other, and how we can gradually animate the morphing to have a beauiful finish piece. It also helps think about we can exaggerate a character's facial expression, to make the animatio look more realistic.
So here are some expressions that I have been working on. (As we work on the animation, I will try to design more expressions for each different scene if needed-this will help see which one is more suitable for each scene).
