The voice didn't turn out ok...
The voice... the lyrics... I couldn't understand them so I dunno if they are any good. But the voice.. men... I'm gonna try to give the benefit of the doubt... perhaps your producer isn't that good or perhaps that was a bad record day... Anyway, in order to give some constructive criticism, next time leave the effects alone, and raise the voice volume a bit (even though I think that might not turn out in your favour!). Even Metal songs have singing so it's important to have the voice properly mixed instead of masked.
