I really like this. I did some interesting stuff with this that I have really done before (I used the record button, for example). I really like how the song came out.
I know where the Chorus stops and the solo starts is kind of a choppy transition, but originally I wasn't going to put in a solo, but when I finished it was just too short and it had very little variation, so I put in the solo and an extra chorus, which made it seem a lot more complete.
I may add vocals, depending on if I ever get to writing lyrics and if I can get my death growls to sound good.
