Ah, what a beautiful remix. I remember listening to the Yellow Card cover a lot when I was a kid, and then I just fell in love with the original by Michelle Branch. After my friend showed me your music, my attention went straight towards the possibility of "Everywhere" being a remix of that very song, and much to my satisfaction it was, and a phenomenal one at that. :3
Don't think it requires improvement anywhere :) Ecstasy to my ears.
