It´s always nice to hear a live instrument. Your master sounds actually nice and clear! I think there might be a bit too much reverb on the guitar, and Gergaloth is right at some points it´s a bit off... Maybe you also should add some bass or something and work make the beat a bit more diverse. The end is a bit surprising, actually... Maybe try to expand the track and find a real ending. I don´t know the original very well so I can´t make a comparison here. Hope this helps somehow. Keep on doing nice stuff!
