Not that I know much.
I would personally like more "presence" in the vocals, I think that you can get that by being a bit closer to the mike. I think the balance could stand that too. Are you using just one mike?
It sounds a little thick too, drop the midrange tone control a bit a crank the high end a bit. See if it sounds any better.
That's what I would do (try anyhow).
Would sound nice with a fiddle backing too, if you have a friend who want's to play along and you can figure out how to lay down another track, what software are you using?
