Good job.
This is a great piece of Heavy Metal. I enjoyed the fast pace introduction to your song and enjoyed the way you changed the speed and tempo of the song up throughout the entire thing, going back and forth from fast to slow. The song had a lot of variety and was great to listen to. I think this would be a pretty good song if there were lyrics added to it. My favorite part of the song was the part that started around 3:25 where it seemed to pick up even more than anywhere else in the song. Nice fade out at the end also.
