As a fellow metal head who has heard down and coc, which I can totally see are influences on you, bring the bass in there as the previous posters stated. The kick could come up alittle, it sounds as if you put a low cut on pretty high on the guitars too. I would say probably what around 200-250hz? It is lacking that low punch from the guitars. Did you double track the vocals? If not, you put on alot of delay and reverb. If that was the effect you were going for that is fine I suppose, bring out alittle more presence in there for the guitars and vocals as well. Bring in that bass to fill in the sound alittle and it would be a killer recording.
