hey, this is pretty darn good! i just listened to many mp3's on this forum, and many of them just have sucky singers--they can't sing on pitch at all! but i don't have much to say about your singing--sounds great! you have a nice voice, and this music-style exemplifies your singing.
my own suggestion is to bring the singing out forward more. sometimes it's a little crowded by everything else. so, i'd like to hear a little bit more of the singer. and if i were really picky, i'd say the voice is very slightly muffled and could use a more rounded and thicker tone (perhaps try to mix in some backing vocals or vocal harmonies?) but that's more of a feeling i get... can't really recommend much else.
