I'm not sure I agree with everybody above in assuming that, just because a short film is fantastic (which, don't get me wrong, this is), a feature-length one would be as good. An actual feature-length movie needs extensive plot, cinematography, lighting and pacing work, amongst other things.
The problem with Street Fighter in film has always been the bare-bones level of plot development - the game was meant to be played on an arcade machine for five minutes before you walked away in frustration to get more quarters. Making a full-length movie that would be bearable would require fleshing out an entire backstory for every character which doesn't involve "Character A beat up Character B at some point in the past, resulting in Character B wanting vengeance".
