I love the tone of your voice and you use it well. Given the dark theme, I think the song should have a hard rock edge and the vivid imagery would lend itself well to a movie or tv soundtrack. You could cut a cool music video using footage from Vikings! Not legally, but you know what I mean. It would be a good fit.
I’m not sure that the style is commercially viable…Is that even a direction you would want to go? If I were you, I would look into getting your music into films. Check out songroller.com. I licensed a song through them recently and they were easy to work with.
You might want to spiff up the production a bit before submitting to any opportunities. You’ve done a great job so far, but I think the drums need to sound more natural. I could help you with that if you don’t mind working with someone in a studio 1400 km away!
Thanks again Kurt.
BTW I liked your Enderman Jones stuff too.
