This was my first time to use Ae to make animation. I felt the difference when adding gravity to different kinds of tings, such as the heavy and light ball. With only imagination, it is hard to me to think about how they might land and jump on the ground. In this case, it is better to try how the balls will fall in the real circumstances. This can apply to many other situation. For example, when I don’t know how characters react to certain things, I can act in front of a mirror and get inspired by the reactions.
The hair of the girl should be lighter and move less than I draw in this animation. In my animation, the hair seems like to be alive as they jump up themselves. What I learned is that I should always keep the volume of objects the same while they are moving.
