Sounds like you're out of tune at times, especially on the higher strings, check your intonation (or tune your guitar) man.
Your rhythm playing is pretty good, but your lead playing is letting you down, especially your bending and vibrato... Marty's phrasing is a bitch to get right though, however it just seems like your bends are half assed. Know which note you want to bend up to and bend it like you mean it man.

Overall I'd give it 7/10, it is a hard song to play.

It's a Megadeth cover as well, a lot simpler than Rust in Peace but still :P I'm gonna cover Take no prisoners next
Thanks for the crit man, some of the best I've received. Right now I'm on my phone but as soon as I can I will give your vid a crit
