Despite the somewhat grisly subject matter, this is such a remarkably warm and (in a way) old-fashioned submission - it is a joy to watch it. The sound effects were what made it great, and the smooth graphical style. The editing was really nice as well. The only thing I would ask for would be a voice instead of intertitles (you had the voice at the end, so why did you not record it for those lines?), and slightly better drawing in places (it was mostly very good, but the thumb on the paper at the beginning, for example, was a bit off).
It reminded me of such Newgrounds flashes as "Nim's Winter Tale" (check it out if you haven't seen it), and it really is very different from most of the things on this website. If I were to venture a guess, I'd say that you're probably older than the vast majority of users on this website, just based on the style of your animation and the attention to detail. Most people are not nearly as good on their first animation, as you may have noticed. :P
One thing I was a bit confused about - the ending. How did it relate to the animation?
Overall, I'm eagerly looking forward to more nice things from you. This flash is going into the favourites box, and into my Top 10 for this month's voting. :)
