Moody...
A few things to say...
It sets a powerful mood, kinda down yet determined. The melody makes it sad and kinda dreadful, but the energy forces you forward. Not sure how to say it other than that. Overall you did a lot of things right with this song. I mean, it's pretty awesome.
But... The first 30 seconds of the song could've used a bit of work. It's kinda draggy and not very interesting. If it were just 10 seconds or so it'd be no big deal, but the fact that you waited 30 seconds to get to the point of the song kinda makes it lose its point.
I almost stopped listening because of that. But I didn't and I'm glad, because the rest of the song is great. So moody. Overall I like it.
