Great job bro
Very good song. I like the melody line very much, also lyrics are awesome. Guttering, yeah, I'm accustomed to screaming and I think this part pretty suits to this song. And as N3XUZ said, great mastering.
But still 9 not 10 for sounding in few parts too much like screamo.
PS. Dunno how do you make such a screaming, or whatever you call it, just do not make your throat bleed, please, because you have a very good voice ;)
Well, I'll be waiting for more productions like this one.
