Solid Drawing

The solid Drawing helps find out the final kinks of the animation. And make sure nothing is out of place or the same "Twinning!"

Staging

Staging is another major principle in animation and this is one of the final steps. This is where you have to decide what you want the end result to look. Worrying about the close-ups and the wide frame etc.

Appeal

So the next principle of animation is appeal. This means the appeal to the audience of what it looks like and feels like. It must look appealing and also feel appealing. The character must have an appealing personality. 

Anticipation

Anticipation is another key element of animation because the audience knows what is about to happen. This also creates more drama and a new level of excitement. So making this swing back of the punch makes this scene more intense and interesting.

Slow up and down

Making sure the things look more realistic is always the job of a animator.  So in the aspect f stopping and starting in life it takes awhile for something to get a move on. Physics is a part of animation.

Arcs

Arcs are used to help see where the movement is truly going. These arcs can help find out what needs to be fixed to look more natural.  Then using the graph editor can make theses changes very easily.

Exaggeration

Exaggeration is good in moderation. Like most thins in animation, if exaggeration is over done it can the soar on the eye of the audience. In this section, we used just the small movements of the face to tell a store itself. This is what exaggeration can do when used well.
