Checked out the provided link. Not bad. If it were me singing, I would pick some of the non-growl vocals and sustain my voice more between phrases as the song built up. Though this may be a change to your style since I'm not familiar with your band influences you listed. I am more influenced by bands like Black Sabbath, Six Feet Under, Pantera, the doors, and Blue Oyster Cult.
Thanks guys.
It's good to hear.
