Pretty cool Vesuvius!
Sounds like you've got some compression making the volume on the guitars or possibly the whole mix pump in places. The guitar seems to thin out a little here and there, perhaps it could be doubled a little tighter. I also think the guitars might sound better with actually a tad bit more gain, just for a little more bite. I dig the sound of them tho.
The vocals seem a little too loud, I would like to hear them brought back just a little and maybe a touch of reverb or something to make them blend in with the mix a little better.
Cool stuff!, don't mean to sound too critical - just want to help!
