Overall, this is a nice piece of work. I really like the twist of tune at around tha lte 0:40, the wicked guitar and all. The background guitar was really good too, great job on that as well.
the part at 4:00+ was a bit...funny. Didn't really like that part, because I was hoping for something really really 'wicked, but apparently that wasn't enough.
Liked the softening end tho.
7/10, good job.
