I was resisting scoring it, but I want to comment
Well I'm not opposed to having more singers on newgrounds but there really isn't a video attached to this. So it really doesn't belong in the Flash Portal. However the AP is a harsh and often lonely place right now. I guarantee complaints about the sound quality there. Your singing is good for the most part and it sounds pretty. There are however several unpolished parts. Trouble spots appear at the end of lines especially if there is a quick line afterwords. Also problems when you suddenly raised your voice higher in the highest part. I feel like you weren't relaxed enough in the beginning of the song. I'm sure you could become very professional sounding if you kept at it.
If I scored on sound alone it would higher than a 5.
