How to improve this mix ?

I like the way the vocals are double tracked and panned left and right but it seems a little redundant. And they're hard to hear at some parts so maybe a +1db gain on the compressor.

Also some the double tracked vocal parts could be more centered in my opinion and that would totally add some diversity to the mix overall.

Sounds fuckin brutal! Great work and keep at it.
 
maybe you should do some EQ to seperate the tracks and add some clarity. it just sounds like another loudness war wave.
