You've got some good guitar playing, interesting riffs and stuff. I thought the way some of the extra guitar lines came in was a bit awkward though, like a 1:00, and then later the ending i thought sounded a bit messy, like starting at 1:35. But other than that i thought the guitar playing was good and the changes from riff to riff was cool. Adding drums would also be cool. Anyway, 8 points for the guitar playing, -2 for the couple things i mentioned.
Please contact me if you would like to use this in a project. We can discuss the details.
