Ok, so I watched the your video first, before even reading this article, and have not watched the Civil Wars version yet. But what I noticed while listening to your performance was that I never craved the original over your rendition.
What I mean is that often, when an iconic song is reproduced as a cover, even if it's pretty good, I will find myself still waiting to hear more familiarity. Such was not the case with your cover. As the chorus came round again, my mind was already looking forward to your phrasing and nuances.
Now I have to go listen to the version on which you based your cover, but let it be said, you nailed that song!
Have you considered entering one of the open mic contests? You really should.
