It actually sounds pretty good man, the kicks need a bit of a volume nerf as when they come in it kills the guitars a lot. But other than that I liked it man, it obviously has a different tonality to the original, but as a song in itself (as in your version of it) it all seems to work together, blends at the right freqs etc to create a pretty punchy sound. Other than perhaps finding some more realistic string sounds it's a pretty difficult one for me to say on what to improve, it sounds good man. Just maybe try a touch of compresion on the master to beef the whole track up.
