A quick modifier: In my review of your story I initially stated that the voice bothered me. I was not clear in what I meant and didn't exactly state my true meaning. What I meant was that I don't like present tense writing. If you can manage to pull it off where it doesn't sound like some teenage girl's fantasy you are really scoring well with your writing.
First person narrative is very difficult to pull off, as well. Judging from what I have read of your writing, however, I think you will be able to manage it quite well. Generally speaking, you will be able to pull off a more full story with third person omnicient because it allows you to fill in any emotions and thoughts that might be important to the story.
