Always like hearing covers of that song. Your voice is nice. It's too low in the mix, needs to stand out more. My main critique is that you stay on one emotional level throughout the song. It's a mournful delivery. The song calls for more power in places. I think you are holding back.
I know you're interested in feedback on your vocals, but the guitar playing could be cleaner and more spirited. It's not terrible. You could improve quickly.
You can always post your covers over on the MP3Clinic. We could use more acoustic music over there.
