it's interesting to note that poser animations almost never obey any of those old disney principles, but pixar (best animation studio ever) obeyed them even before Jobs sold it to disney.  people might say that poser animations are usually unwatchable because they don't even bother to render them (just preview animations) and the lighting sux, but maybe even a rudimentary poser preview animation would be more watchable if the animators were open to criticism.  in closing, for god's sake don't put one of those nostril-glow preview animations in your demo reel if you want a job around here (silicon valley).
