wow, you are really cranking out the animations! is it possible to NOT love these characters?! I do agree with Jake that at one point, the yellow guy doesn't seem to be laughing as hard as the sound he's making.
I'd love to see these guys in a street scene, where everything on the street is alive with their own personalities - mailboxes, shrubs, those free newspaper boxes, trees, your lightpost guy, etc...
great work!!
