Absolutely great
I love it when I find stuff like this on Newgrounds. Folk Metal is such an overlooked genre and metal in GENERAL is even more overlooked here on NG with the massive crowd of techno/electronic songs that fill the audio portal. This is literally a one in a million thing to find, and I just happened to see it on Oney's page. Kudos to his good taste, and def kudos to you for making something incredibly creative and badass at the same time.
