Lessons to learn from traditional animation

This article was about Jay Jackson's lessons you can learn from traditional animation. Jay was trained under Eric Larson who was one of Disney's Nine Old Men, the big time animators at Disney. Jay learned that when he first started animating, just how important the posture of bodies are. He was dissapointed at first when he saw Eric's crude drawings, but after seeing them in motion he discovered just how important these key poses are. Jay also learned how important of trying every possible conceivable pose is. It's important to get across to the audience the mood and motion of the character, so everything must be tested. Jay finishes by saying how important it is to spend half of you're time thumb nailing and planning and the other half animating. The more time you spend planning, the better you're animation will be.
I thought this article had some very useful information in it. But I thought there would be a few more points in it honestly. Most of the article is describing how he was critiqued and not a bunch of juicy tips. But still the information in here is very useful.
