Have you put it to music yet?
What kind of music do you play?
If I were putting it together, I would come up with a refrain or chorus and shorten it a bit. It should play, with riffs and everything, about 3 or 4 minutes. You should iron it out immediately and get a copyright as soon as possible. You shouldn't be posting this one on the web. Get it documented and send a hardcopy with your name and date to yourself. When it arrives, DO NOT open it. Just file it away incase you have to prove when and that you wrote it.
Keep up the good work.
