I decided, to get myself into a bit of reading to maybe inspire some ideas by reading a chapter out of the Illusion of life book. I read about Fred Moore who worked on many Disney animations. It talks about his ability to pick up skills really quickly and to change from using rubber hose animation.
He liked to show the characters think, having them go from a frown to and eye roll and the face moving. From what I gather, he seemed to progress Mickey Mouse to use squash and stretch, it talks about how his animations looks like they had more life in them and felt/looked better and seemed more real because of his ability. He always thought of what was a nice, pleasing drawing.
The new things he would think of would be based on what he thought looked right not the analysis of it. He would only pick a view that would look pleasing to him, so when one time he was asked how Mickey would look if you were looking at the top of his head he replied "why would you?" If you had designed a character based off of its balance of features then why would you deliberately show it at a point where the character didn't have much going for it.
When he was working on Snow White and the Seven Dwarfs, Walt Disney would sweatbox all of Fred's early animation for the dwarfs. Walt kept picking up on him drawing a finger too large in one scene and Fred would keep putting it off.
Often when Fred would get a test back with a mistake on it and he would say that it was always on something basic, something that he had known for years just cause you always have to forget something. And this is where he decided to make a list of 14 fundamental things an animator shouldn't forget.
The book goes on to say that his childlike nature really showed in his animation and Marc Davis said "Fred Moore was Disney animation!"
