Well, I wouldn't call it awful, for it's really not that bad, but it sounds very...
mediocre. I mean, 9 out of 10 aspiring metal vocalists could probably produce very similar results. If that's enough for you, fine. But if you want to impress others, mediocre is not enough when covering a unique vocalist like Stanne.
I didn't want to start a new thread for this and I'm not sure if this has been posted on this forum already, but here's a rather unique DT cover:

Note that the vocalist of the band isn't a particularly great one, but his "whiny" (for lack of a better word) style goes perfectly with the sharp tone of the strings - a very powerful death metal vocalist would be a far worse match here, I think.
I'd really like to hear stizzle's thoughts on the clip.
