I don't even mind the art direction as-is (not speaking for previous commenters). The way I see it, is that the choice to use 3D character models (not my preference, but a given) also calls for a different style for backgrounds etc. to make everything blend together. I think if even more effort could be put towards smoothing things out I could still be perfectly happy with the end result. I remember watching behind the scenes videos from Iron Giant (and I believe Emperor's New Groove) that showed how much trial-and-error the animators went through to blend in CG with traditional animation befo
