Totally awesome movement! i especially love the facial expressions, you're a born animator.
I have to ask, since I'm dabbling in traditional animation myself, how do you get some segments to move without dragging the stationary background with it? I realise there are two layers, but how do you do that so clean?
Oh man, one of my instructors in College (Henry Cogswell College, Everett Washington, USA) included this piece in a folder full of animation clips that he considered "worthy of study" for students in his Animation II class I took.
