I found this short extremely disorientating, but I truly liked some of these scenes. Maybe this is the effect you were going for, a sort of assault on the senses... that or my mind is far slower than your own. I disagree with the poster who said it wasn't crowded -- it is, perhaps too much so. I wanted some time to process something... ah, I don't know. For instance with the spiders, without giving that man a face, I sort of felt like the scene was too empty. Like an idea that doesn't go anywhere and stays empty. If this is something you intend to study or pursue furthermore then maybe it needs a bit of tweaking. Jesus, this is turning into some bad review. Did you want my opinion?
Well, I liked it and as Brutus said, very impressive, because I've tried shooting things before, and this final product looks very accomplished. I don't know if I'd be able to handle more than half an hour of these slices, and I wouldn't tell you to try and expand on them, but hopefully we'll be able to see more of an extended piece in the future.
