Hey its pretty good music. I like the sound and the feel to it moderen 90's all the way back to mid 80's. I also love the distortion.
Though since it was a song, and not a freestyle, I cant really crtiqe you on your guitar playing. Your medody and sound is cool, but not so sure about the actual difficutly. Since you were playing basic power chords, I cant really say much.
*put a killer solo at the start to grab everyone's attention and then go to the basic melody pattern.* well, thats would I would do
