wow that must have taken a lot of time to learn! in my opinion you have to work more on the groove and rythm (maybe you are not hammering hard enough to keep a constant volume) to get closer to the original, i know it may be harder but you are really on your way man, congratulations!

That was pretty good and far better than what I can do, but I'd say rhythm was off during the hammering... I think if you would keep working at it to where it would be a more natural feeling to play, then it would sound a lot better. Keep up the good work though!
