Here's the issues with it. -- Guitar tone is alright, but personally I would probably experiment around with it a little more to give it more chunk. It seems kind of thin in my opinion. -- The timing. The timing is kind of off. The problem is that it is quite noticeably off. The thing is-- with metal guitar parts and harmonies they have to be RIGHT on or else they lose their effect. I mentioned in an older question you had about the flex tool. Also, are you playing with a click track when you record? -- The part itself. Besides timing, there were also some issues with accuracy. For instance, there were some missed notes. Granted, that could of sounded that way because the parts weren't synced too well (hence why syncing the parts is important). Besides that, I'm pretty sure the chorus is not palm muted when Shadows sings "... COULD BE THE ONE." For looking up tabs and stuff I suggest songsterr. com -- The black and white video may be too much. That is just my opinion though.
Covers in a sense have to be more accurate than A7X actually playing live. It is because everyone is focusing on how well you play and sound. There is an added pressure in that sense.
I feel like you could pretty easily fix the mistakes and issues with it, but for now I'm rating it a 3.
Although i don't know the song, my internal rhythm is saying that the speed is a bit off, you need to practise a bit, metronome the single line riffs till your not struggling, unless of course the song is meant to be syncopated. Great tone though
