i learned the guitar part some years ago, already forgot tho. i never had the patience to look for the piano version^^ . It's pretty good mate. How long have you been playing piano? I've been playing since i was 6, XD
^^ hard makes it sound better^^ . Since i started listening to metal, i haven't played much piano and i started playing more guuitar. And it's twice as hard cuz i dont have electric guitar, i have an acoustic one, so it makes really hard to play some guitar rifts. Here it is the videoclip of the song im currently training in my guitar:
