Interesting, Abstract, Beautiful.
I find this animation a really, really interesting movie. I love the concept of this whole animation, but i am certainly confused, and somehow dissapointed, because i was expecting to see something that tied the whole animation over in just one rational thing, i mean, there was no relation between one day and the other, like he killed the little human and said "I will never regret this" and at the next day he is all like it didn't happened. But still, i liked many things as well. i loved the detal that you put in every scene, i also love the faces, they matched perfectly to the kind of voice you gave to the characters. I liked the narration type of things. liked that it was divided by days. liked the whole atmospheric kind of feel. The Ambient sounds were great. Besides being 30 minutes long, it didn't took forever to load. I believe this could really be a masterpiece, you just need to make everything make sense, take most of what is abstract and convert it into a logical thing. Tweek it a little bit.
I got interrupted the first time i was watching the animation, and missed part of it... so i had to watch it over again until i got to the part where i left the last time, you should add a pause button, or a scene selection, that would let us go to the part where we left, this because its really a long animation.
Thats all, my friend. Congratulations!.
