Troy Stetina - Exercise 10 (thrash metal guitar)

Hi everyone!
This is the third exercise from the Troy Stetina's book "Speed & Thrash Metal", which I learned on electric guitar!
It was quite challenging for me to play as it features downpicking on multiple strings, and I'm still not able to play it clear.
I'm going to start creating music in the future, therefore I added bass and drum parts to the mix.
Please comment and share your opinion on the result!
