Full marks for energy and effort. Your drummer must be pretty tired! Vocals and guitars were really well mixed, and in a densely packed song like this, that's a real accomplishment.
I liked the slight interlude in the middle most of all. Good, thoughtful choices!
I'm not sure the video really helps the song, at least for me. It's a kick-ass video production with cool drone cameras and neat lightning effects! And it is VERY well edited - lots of cool cuts! I dunno, it might have been the grey color palette, just presenting the song without much "life" or energy. I don't think the energy in the video matches the energy of the song. that's probably just me, and most thrashers are gonna love that video . . .
cheers,
