Lots of fun blocking this one out. After a month of not animating it felt good to get back into the swing of it again. I started out by getting a good walkcycle going on Stewie, and then making adjustments to give him some personality.
A big lightbulb went off when I decided to make him overweight - instantly there's more motivation to his character and gave some insight in approaching his walk and movements. I see him as a character that's never in much of a rush and takes his time to get places...until he sees something he really wants. When it comes to the donut, he has more quick sudden movements.
This was also a good exercise in getting more comfortable with props/rigging/contraints. The apple leaves his hand twice, and the donut is passed between both hands. So it was great experimenting with the different ways to accomplish this and learn the pros/cons of each. I think it really helps the animation feel more natural, with the almost casual way Stewie interacts with the props.
