Not bad at all, my friend. Not bad at all.
It sounded great.
You guys ARE metal.
Although I must admit I'm not stoked on this kind of singing. (Grunting or whatever it is called.)
But around 2:10 there were second vocals an immense octave lower.
That sounded like: well, let me try to describe it...
Satan's hot airballoon trying to take off.
To who did those vocals: take that as a big compliment.

It was impressive.
Musicly it was very nice. Beyond nice, great metal and very professional.
Great melodies weaven into the music.
Especially toward the end of the song.
You guys keep this up.
Cheers from me. And respect.
