Very nice cinematography. That focus pull from the branch to those trees in the forest... OMG
However, I'm not so positive about the structure of the film. You didn't really give enough clues as to what was going on until the film was nearly over, which is forgivable for a film so short but very bad if you are doing something longer. Also, the story was too frenetic. To properly set up backstory you need to make it more accessible, and while I understand the need within the movie to create the disorienting effect you did with the 'flashback' parts, you should have figured out a way to make it more understandable. This is a bigger problem because the film is non-linear, which creates even more confusion. Early on in the movie you should try to establish more of a story.
My final criticism has to do with the ending. I didn't like how the backstory was rushed in in about 30 (?) seconds. While the editing was stellar, it felt less atmospheric and more expository then necessary. This is more of a personal opinion, though..
The impression I get from this film is that you're focusing more on the eye-candy aspect. DON'T DO THIS! It can easily wreck a film (Trust me, I used to do it ALL THE TIME). When it comes down to facts, what carries a movie is it's characters and storyline.
(Sorry if I came across as overly tough, it's just that I think that this movie isn't as good as it could be - that doesn't mean it's a bad movie though. It's definitely one of the best student films I've seen so far. If my post seemed overly negative, it is probably because i've been focusing on every single minor detail that could be improved, not because the film was terrible.)
Hope this helps..
