I agree with rancky, but more so in musical changes to fit mood. Sound effects can very quickly ruin a mood.
I have to say, it's a bit drawn-out, but makes me wonder about what sort of metaphor that bear can be. Child-like innocence, comfort, and so on. In the case of innocence, it would be Yasuko, but the bear would be some sort of courageous exploration.
If it were a sense of comfort I would disagree with the message, but if it were something internal or external that symbolizes and embodies the idea of "putting yourself out there", I'm curious as to what it is. Something that I've been lacking and only seldom find.
Outside of this, nice work. :)
