Well hello there lublub. I'm a little late... as usual haha.
One thing I can go out and say right now is that this composition is purely beautiful. The transition between the beginning and the guitar is perfect in my opinion. This is exactly what I think when I hear heavy metal. I really like the drum beat, it really does bring out the most of the song. The part at around 2:23 is awesome! There is one part that I can't tell if I like it or not which is at 2:43 when the high chords of the guitar come in. It feels like some of the chords fit while others... maybe don't? I think you should leave that part in there though, I don't see any reason to take it out. That piano man... it fits the song perfect.
Truly was a great piece, don't know how this is below 4. Until next time, peace man
