aaah dude!!
You had such a great setting goin on! I really got absorbed into the whole sittuation, the misterious creature only giving little signs by knocking, not knowing if it's hostile or friendly, but slowly getting worse by first taking a bite out of the guy's sadwich, cutting of his transport and communication and eventually driving him nuts. And when you finally get there....yeah! Finally we get to see what kind of creature(s) lie(s) ahead!!
....and then we see friggin furries.....
Now that has to be the biggest anti-climax i've ever seen, seriously! And that's why it's of course damn brilliant! I mean, i've never seen an animation or even a real life movie wich is relatively long and is really seriously well made to have such an ending. And i've always wanted someone to make that and you finally did it!
Because, most videos wich have such an ending are either kinda cheap and have a cheasy feel to it, or give it away with slight hints. But you stuck with the serious and mysterious setting all the way until there isn't any doubt of a dark creature of some sort, with vicous teeth or with rugged rusty weapons, that's looking all messed-up and wounded, scarred and all that other scary movie crap....and then comes a group of colourful smiling furry forest creatures with human features! (wich can be even scaries but that aside). Now to make that all the way must require some serious discipline, passion and talent. And you've got it all!
God damn, I can easily say this is the best animation I've ever seen and that I won't see an animation as good as this for quite some years to come.
.....although, now that take a look at your user image and banner on your profile.... I should have seen this ending comming.....
