Truly a great animation. It looked professional and polished (everything except for the stickman part). And you've left me intrigued... What was all that?
I guess the different locations have a metaphorical meaning or somehow resemble memories of the girl... Her fox guide was very cute and her kindness shows that they have a "good" relationship, but somehow the bite unleashes everything that girl seems to be keeping inside... So many questions!
I'd love to see this fleshed out as you originally intended, perhaps it would be clearer. As it is, it's still great.
