Very good job on guitar, but the whole composition is unbalanced. The percussion and rhythm guitar are really soft, and it takes away from the "extreme" that I was expecting from the title. Probably a solid 3.5/5. Great shredding, but issues with balance. Keep up the good work!
Edit: Also, you should add reverb to all of the instruments. I noticed that the guitar had a lot of reverb, but the drums and bass are dry. Not sure if this was intended, or just something you missed.
