Far from useable.
You seem relatively skilled using a guitar but all the skill in the world doesn't change the fact that the extremely poor recordingquality and lack of any backing instruments (drums/bass/etc) completely undermine your very valid attempt. Work on the recording quality first and foremost. I suggest getting a pod and combining that with a computer using a good soundcard and a sequencer of your choice. Then you'll be able to actually upload some very useful material.
Please contact me if you would like to use this in a project. We can discuss the details.
