You have a voice, and you range seems quite on the high end--which would give you the ability to cover more songs. (mine's low, and it gives me problems when I do karaoke)
Your flow with the notes was quite good. In a number of places you were out of key, but I would say that it didn't distract so much from the overall sound. I little more power from the lower diaphram might be good too.
Nice job.
