You know whats better than doing animation?

Answer:  DOING IT AGAIN!!!  Your art never stops improving.  It can always get better.  You always have to push yourself to look at your work, critique it, figure out how you can make it better.  Even though I was extremely happy with my last post and I thought it was perfect, once I looked at it again later on with a fresh, critical eye, I saw lots of room for improvement.  The main lesson I learned from this revision/addition is stretch/squash and exaggeration.  I always thought that in realistic animation, it was stretching the character out into his/her most extreme position while still being able to keep the proportions.  But then we go back to the bouncing ball animations, where we distort the ball and literally stretch it across the page, and then squash it down.  That rule doesnt just apply for soft, rubbery, stretchy balls.  You can use that kind of exaggeration for ANYTHING.  It will give your animation so much more weight if you really push it.
