Actually, you're singing with your head voice which is completely fine provided you are supporting the sound using the correct breath control. I think you have a beautiful tone, and a very natural ability to tune- very good musical ear. Have you had lessons? I think you'd be just wonderful with them. Your diction is also very good, especially if you haven't had lessons. Bad diction is what I can't stand.

Really lovely, could use some work in some places, but hey, there's always room for improvement.
