Hey, the guitar soumds like its off a half a note
It kinda throws off the epicness of the piece. Was that meant to be off key? If so, then you did a hell of a job. If not, you might want to have the guitar a half note higher. Do that and I won't be able to imagine the level of EPIC you'll have achieved.
Just my personal opinion. Keep up the shredding man.
