Poodles.
Good cover, but I definitely feel it could be improved.
I like the actual guitar sound, but I have two gripes about the guitar: The stops are too sudden and there's not enough dynamics.
I'd suggest using effects on top of the Slayer guitar, instead of relying on the slayer plugin's own effects (apart from a few guitar-specific or slayer-specific effects like tremolo, although I use Guitar Amp Pro on top of it for that). For instance, I have a preset I made I call the Screw Guitar which is the Slayer 2 plugin with Guitar Amp Pro, Stereo Spread, and GoldVerb over the top of it.
Another thing is on small note changes, you could try using a pitchbend to change to the desired note instead of creating a new one - this can make the guitar sound more natural.
