Hi. I'm sure it's difficult for you to sing your best while focusing on guitar but your vocals will improve as you become more confident on the guitar. On Tennessee Waltz, I didn't feel you were projecting enough because you were holding back. The guitar is taking away from your vocals and vice versa. However at 1:16 into the song, when you were feeling it, it was great. You weren't thinking and it shows. I felt the emotion right there. So, my opinion...which you can take with a grain of salt, is that as you improve on the guitar and become more confident, your vocals will improve also.
