I can agree with XTREEMMAK on a couple things,
The guitar, again was solid.
Drums were, just like every song I've listened to from you is great and always well kept with the beat..
IMO <-- ~ If you we're aiming for aggressive , I recommend sweeps.. I don't know if you like that style or if you're learning it now but even just 4 seconds of sweeping would add a deep feeling of aggression and a strong hate for whichever reason you were aiming for with "angry" .
Not to mention flashy and to most people jaw-dropping. =D
Nice Duox , Great work!!
