If you want it drawn and animated with a pencil, think of XYZ.
Of course they do a lot more than this, but years ago it was a pencil drawn style animation that drew me to their work, and i see some of this throughout their reel still. This is a Director collective based in Australia, they do a lot of character driven work, and their logline sums them up i think very nicely: XYZ creates worlds. Pencils, paper, cameras and computers are the tools. Storytelling is the art.
