1. Turn down your cymbals, they are alittle too loud. You may have wanted them to a present part of the music but when you hit a crash it drownded out the guitars a bit. I'd turn 'em down about 2 or 4 decimals. Not much, just enough to blend them back in with the rest of the music.
2. The low end of the bass is there, but I can't get a sense of the rhythm or notes it's playing. Check out the link Simon wrote, I wrote the frequencies you should boost alittle to make it more apparent.
Other than that it was a great mix.
