Too static, but really nice melodies
Strong performance I must say, And I will do as you say, judge the song based on composition and not the instruments used, because the FL Slayer really is an earsore :D
I think you Have made a really good job with melodies and the dramatic feeling.
I have a slight problem with the drums though, they stay the same throughout the whole song, and I can hear the basedrum's "ta-ta-ta-ta-ta-ta-ta" endlessly. I think you should try and make this song more dynamical in tempo and at some point skip certain instruments and just play the melody, or something like that, even battles have their ceases you know. I won't let the instruments or production keep the score down, so I say 4/5 7/10 as i see it has potential
