I'm getting a strong Hitoshi Matsumoto vibe from the mock-documentary style of this, reminiscent of his classic BIG MAN JAPAN, together with something like Minoru Kawasaki's EXECUTIVE KOALA. The effects work looks absolutely sensational - the expressiveness of the "puffer face" is incredibly emotive - and quite frankly I cannot wait to see the full film.
Check out the trailer below and there's also a link to Robot's website so you can check out their back catalogue of excellent videos.
