ugh not another metallica cover. its a good attempt. when you're playing those chugga-chugga palm-muted parts try using only downstrokes..when you're palm-muting its easier to tell the difference between a downstroke and and upstroke so it gives a very uneven texture to the sound. the guitar volume for was very low for me to make out anything else to give you as tips tho keep up the good work and if you can play this, try attempting the forest of october by opeth. you'll find the tabs online..its a 13 minute constantly progressing song but once you learn it as a whole you'll be very proud of yourself :]
