Good stuff!
I'd say viking folk metal because I feel like in a mood for drinkin right now. Na, it's still prog. black metalz! ;)
I liked it, nice structure and good constant vox. Now I do have a couple of pointers for you. I think you can blame the quality on your recording equipment. At least that's what I think. Let's start with the main thing...drums. They are very, very weak in the song. The kick is audible but is has no power to support a track of that caliber. There is no beef behind it. The snare is hard to detect as well. Just like the rest of the crashes, symbols, etc.
It's not only the mixing, I think equalizing the drums would be an option here too. As soon as the track starts, the bass kinda says good bye! I do like that tone very much but it doesn't shine through the hole song.
As for the guitars...They are very thin/clean and sound to compressed/isolated. Missing some mid highs there. >:U
Vocals and Piano are the things that really don't need any adjustments. As said before, I think you can blame the quality on your recording equipment. I would take this track and re-mix it again. There's still a good portion of potential in there.
Overall, I enjoyed the track and I'll give it a 5/5.
Keep it up!
