You are a perfectionist, aren't you?
It sounds like a second take from the original. I don't think I would say it's a different recording if it were replaced by the original version (of the New Moon soundtrack).
There's quite a lot of reverb going on, which is great for the mood of the song, but I can't really hear your voice clearly, because of it. That what I hear, sounds great, though.
Keep it up.
