hmm, i think the guitars are completely wrong (mix-wise, musically theyre savage!). cut out some of the high end, throw in ALOT more mid, and maybe a bit more low end. and it sounds like there is a really tight noise gate, but i could be wrong. if there is, loosen it up a bit.
the snare is nice, but i think it is really weak. maybe add some low end in there just so it punches. if you want my honest opinion, i think you should try a whole new snare sample. as cool as piccolo snares are, theyre very hard to make sound sick, because they just sound so weird lol. for the same vibe, i reckon you should DL the joey jordisson snare sample (its somewhere on the internet. i was gona link you to the site i got it from but its been removed lol).
the intro guitar sounds really cool. its really unique sounding. maybe not a sound i would go with myself, but each to their own, its really unique, so i reckon if you like it, keep it
the toms youve used sound sick, nothing to complain about there

same as the cymbals
the kick drum is nice, but maybe add a bit more low end
and the vocals, maybe take them down in the mix a bit, and add a very slight amount of church reverb
hope i helped (probably not

)
