Not a bad little film
I'd say the greatest asset would be the length. It doesn't cut off after a couple of minutes like so many portal entries. The drawing and animation is up to par, story seems to be sufficient. However, you really must remember to credit your audio source. In this case, it's Emerge, by Fischerspooner, in case you got that off Kazaa and you're not sure if the file info is correct (happens all the time with electronica).
Keep it up.
