After I refined storyboard, I made this animatic to check the timing and story.
While the story is still too complicated. Neil suggested me do not waste any of the animation. The beginning should be simple and clear. Besides, this short film is for children. Those violent scenes should be removed.
What should I do next...
1. refine the story again and again
2. think about the characters' facial, e.g. eyes, mouth...
3. test the style of this animation
