Had my doubts at first
but this proved to be amusing. Even if it is just a scene for scene transfer of the commercial, the animation was pretty decent and the idea of using hetalia is fun.
I have to take points off for originality though. The jokes and premise are exactly the same as the commercial, almost down to the very movements of every character, which, although not terrible, does diminish the quality of it as an original work.
Seems like you have lots of talent though, keep it up. A lot could be done with olympic themed hetalia flash :)
