I love New Moon so much. I'll give it listen and let you know what I thought.
What I liked: the guitar sound was awesome and had a nice balance (3 guitars?). I also thought the glockenspiel thing was a really nice touch. I also like your voice in the upper registers.
What I thought could be improved: When you sing in the lower register your voice is a little too strait. If you know what I mean. Not as nicely expressive as when you sing higher. I would work on that.
Other than that your arrangement was a nice touch to a great song.
