This is very epically sad
This sound like the scene where the good guys in a battle are losing terribly and everything slows down through the eyes of a captain that has lost hope of winning the battle. looking at the dead around him and in the distance he sees his front lines being demolished by the evil army.
its a very sad an epic song..i thinkk you could have made it a little more powerfull.. like maybe adding some timpani rolls
yes this story could fit very well with the song, for some reason I did not think about timpani, which is why it is not in the song, though timpani is a very good suggestion.
