Principles of Animation

Straight Ahead and Pose to Pose:

These are the two different techniques you can use to create movement in an animation. The first one you have on the animation is Straight Ahead: all the images are created and if you play them fast you see a movement. The other one is Pose to Pose, you choose the key moments of the movement that you draw. You link them together after to create the movement.

Exaggeration:

Exaggeration is used to add more appeal to a situation. It can be used to created a more cartoony movement or if it's a rather real cartoon, it can make an effort clearer to see. In both situations, you want some degree so that it's not too odd.

Follow Through and Overlapping Action:

Follow through basically says that some parts of the body keep on moving even after the character stopped moving. Overlapping is about the fact that separate parts of the body will move at different times. Since in real life, every part of the body moves at different moments and speeds so these things make movements more realistic.
