Nina Pailey, who was the creator of that one is making another film - or as she puts it, it's a "potential-possible-maybe- feature film"...
Anyway this little clip I understand is meant as perhaps the ending scene of that big project.
Looks great!
(And it could have been done in Anime studio.)
You can read more about it at her blog:
