Nice work mate!!
You mentioned to me last week about showing you how to play it, if I recall?  OK, I should be up and running to post clips this week (touch wood!), but I thought it was pretty much fine (apart from the one bum note, but show me a player that's never played a bum note and I'll show you a liar!!  :laugh2: 
The only suggestion I would make is that the intro has to be very precise.  So at the end of the first bar, when you go from the high G (1st string) to the A (3rd string) and then the F#(1st string) to the A (3rd string), try to make those notes as disntinct as possible with practically no ringing.  So don't barre or mini-barre the strings to play that (thats what it sounded like you were doing to play it).  Play individual notes. Repeat that same technique in each measure throughout the intro. You're almost there and with that sliught technique change, you'll have it nailed mate!!!  Don;t take this as a criticism - its good - it's just you asked me how to play it last week so I thought I'd really listen to your clip and help how I could...
Playing it at gig volume through a driven Marshall, you have to make sure each note is REALLY distinct, so it's good practice!!! 
Nice stuff...
