The description says its a promo short for a proposed full length feature. This looks really amazing. When I was in art college one of the instructors brought a bootleg video of 'Akira' just to show the class.
It really blew me away, I had never seen anything like that.
The same instructor worked at a local comic shop and pointed me to the old Epic Mobeuis books.
Thanks to the internet the world gets smaller and smaller!
