You should be pleased that you got a nomination for a first attempt, that's pretty good.
For a first video, it's really quite good. Are you already masking in your first video? Technically speaking, there isn't anything really objectionable in your execution. It was pretty solid overall and nothing jarringly garish or crude. Effects were restrained and used to emphasize synch with the audio. I thought it was well done. If this is your skill with your first video I think you're going to be making some really good stuff if you keep at it.
Personally though, although it was composited well, the visuals and the song are a tad on the mellow side. While editing is frequent, the pace of the video seems to drag, only because the visuals and the song never really change the entire time, so it sounds like one long stanza really. I suppose a little more focused story telling would be a good idea, because I wasn't really sure what you were trying to convey, outside of the fact that Chi is an electric girl. *shrugs*
Video: Quality is decent, but I think it's lacking in color. I think a bump in saturation and contrast would benefit.
Audio: Good quality
Editing: Good flow and consistency, with some good sync.
Effects: Restrained and with purpose. Not particularly impressive, but they get the job done.
Overall: Albeit a tad boring, it's constructed well. Better concept and I think your skills will take you far. 7/10http://www.youtube.com/watch?v=n0oNUm6zKlA
Here's my newest video I just completed. Feel free to rate, and it's only my second one personally. Hopefully you continue to make more as I will.
