Wow man, impressive
First of all, native Japanese speakers sound 100 times worse when they try to speak English, in anime at least (Fate/Stay Night, Black Lagoon, Bleach, Speed Grapher, etc). So I have no qualms there, the Japanese added to the style, which brings up my next point.
Nice style - Holy crap, that was incredibly intricate. So many characters filled that 5 minute clip, and some of them were drawn only to appear one time. The love triangle, the fox dude, the scientist lookin' old guy, the cannon; everything fit together so fluidly in that short amount of time. I am jealous; I can't even get real film with that much style. Anyway, while everyone else is stereotyping anime; I am just going to say good friggin' job.
