Its just one riff. I mean- its too early to say if its good or not. Anyone can make up a guitar riff, the real talent lies in the way the riffs/song progresses over a period of time. Keep up the work.
Now that I think about it that wasnt even good. Here's a new one http://www.fileden.com/files/2008/8/11/2045823/New%20Song.wav Im too burnt out to do anymore, hopefully I can figure out a solo tomorrow.
