Death Metal is definitely not my cup of tea, and I imagine that of the Viking persuasion isn't either. Nevertheless, I shall endeavor to render fair judgement unto you.
Let's get one thing out of the way, right off the bat. I think the lyrics sound goofy. Not the screaming scratchy stuff. That actually sounds cool. But when you do that fake sounding deep voiced stuff, like "A cloud of Weeping Lilly pollen is unleashed," it just sounds silly. Maybe that's how viking death metal is supposd to sound? Not sure. Oh, I absolutely love when you say "rrrrrrragnarok!!" Awesome. I think though, that the voices are sitting in a weird place in the mix; it sounds like you recorded them in an empty coffee house or something. I don't know, something about the reverb makes it sound like it's on a stage in a small room.
Anyway, as for the actual arrangement of the source music, I think you did a good job. The guitars rock out pretty hard, and the percussion keeps the energy strong without getting old. Nice.
Perhaps other Js will have production qualms, so I'm going to reserve my final vote until then, but for now, call me borderline YES.
I've been letting this ruminate a while and I've decided to change my vote to NO, resub; I'm just not completely satisfied with how those vocals sit in the soundscape. Vocals like these shouldn't sound so cramped and small.
Oh, and I just want to add something as an aside here: when a piece of music is described as being a miniature world, that is what people perceive through the music on its own. When you truly create a piece of music that transports the listener someplace else, you don't need to write out a back story for it for people to read; you don't have to explain the music. Let the music speak for itself. Just my 2 cents.
