I always find it interesting, how other players develop a method of strumming for acoustic guitar. If you don't mind me asking, how did you come about with this particular style for this song?
Eternal Sorrow really through me off guard. With the art chosen and the track title, I was expecting a black metal track! I think a bit more reverb on the vocals or bringing the vocal level up just a bit would be beneficial. I like the galloping strumming pattern you play throughout the track. Though I'm not sure it'd be the direction you'd take this track to, I think it'd be great to hear drums and bass here.
