Everything marches along with each other. Very clean sound. I'm sure I'll have a different opinion when I hear the vocals, but: The guitar seems to be the star of the show at every fill, it might be interesting to have the bass to a quick downward scale during a fill with the guitar palm muted to emphasize the initial attack of the bass notes.
All in all, this is a great track. 5 stars even without the vocals.
Please contact me if you would like to use this in a project. We can discuss the details.
