Absolutely great work! It's so immersive and it ends so abruptly that you are just left wanting to see a little bit more!
Unlike some of the other reviewers, I actually enjoyed the narration and the way in which it was written and read - the word choice, the tone... I also enjoyed the little specks of humor here and there.
However, the idea of having the protagonist talking while the narration was going on was a little bit bothersome. I mean, you have the advantage that her dialogue was more of an atmosphere-setting thing, but, naturally, the viewers attention has to split in three when she speaks: they have to follow the animation, the narration and what she says. It's disruptive. I didn't hate it, though (it is an interesting tool), but you should probably find someway of easing that multitasking you are asking for. Something as easy as stopping the narration while the girl talks could've helped.
Anyways, I loved it. I'd love to see a more polished version or a sequel. Good luck on NATA!
