Thrash/Death Metal basic riffs (Lextac,TSE BOD,SD MF...)

sounds a bit middy/dark but it works
kick is cool, snare is not really audible, and I guess its overcompressed too
 
I like the riffage, reminds me of my own tunes of late. Guitars sound a little grainy and loose like there's no o/d boost pedal in front but in a way that's good. The snare sounds a little fakey, you could try a transient designer on it might sound a bit more sustained and less choppy. Otherwise it's a nice powerful mix if a bit dark like Marco said, comes across well.
 
sounds pretty good but i think you could do with a bit more presence in the guitars they dont need to be louder just that they need a bit more input gain maybe? not really sure what it is but the guitars a little bit too muddy for my taste, but if you fix that then this will be great
