You can play the notes, which is good. I thought the parts themselves were well constructed, if technical is the route you're taking, and I'd definitely need to practice those lines quite a bit if I were to play them. However, simply playing the notes isn't good enough if you want to exist at the top. Frankly, it doesn't make me want to bang my head, if you catch my drift. I know "make the bass sing" is one of the corniest things anyone could ever say on a metal forum, but to take it to the next level, try making your bass sing like a metalhead full of wanting to kick somebody's ass. I'm sure Steve or one of the other regulars could give you better advice than I could, but I hope that helps a little.
