Not easy to mix this kind of music for sure. On the guitars: they are very bright at the moment and that makes it very hard to make the mastermix work. I tried to fix it on the mastermix, but by making the guitars sound better, it affects the rest of the mix as well.
On the guitars, as a starting point, EQ out a big bell at around 700hz at -5db, and EQ out another bell at around 3k at -2, so basically you're getting rid of a lot of mid and (a little less) high mid.
