Wow.
This would make a great live-action movie. I can't think of one thing I didn't like about it.
Just a observation, though; in the black and white scenes, I noticed that there were a couple of black bars that would move across the screen to simulate bad quality. FYI, thos bars only appear in broadcasted video, not on film, which is what I assume you are going for, the scratchy silent movie film look.
Otherwise a damn good piece of work. I'll be waiting for 2/3 and 3/3.
