wow that is a really great song. I don't know (no pun intended) what you have in mind for this but I heard it a storming ROCK track. Great riff and really good melody simple but effective hook. Bloody great!! But what to do with it. If you don't have band, then perhaps try to find one that could really give this a run for its money. It is short at the moment but an arrangement with extended intro outro and of course a guitar solo would really work with this. The riff is outstanding.
Of course it might be that you want it to be a nice acoustic song - and as that it is fine, but as something heavier - it would really catch fire. I hope this helps a little. All the best. BTB
