I consider Dan Haskett to be one of the finest animators/designers working in animation. One of the things that is a mark of a Haskett design is the immense appeal that he brings to his designs; his character designs are constructed of streamlined and animate-able shapes. Here are a couple of his designs as examples. I'll try to scan more of Haskett's drawings that I have in my collection and post them here.
