It may be unfinished but sometimes that's probably not a bad thing. IMO the bass would just be inaudible, too much and probably dilute the initial heaviness you're going for. Overall this is a really great composition and that part at :57 was pretty Bodom, it gave me chills. Awesome, great job!
if its unfinished, then you're going the good way.
Please contact me if you would like to use this in a project. We can discuss the details.
