It's clearly not autotuned! I can see why they would accuse you of it, though. Listening to the 4:43 mark, it certainly has that autotune "style," but before that, I can tell you flubbed some notes throughout the song, especially that first "yoooouu" high note.
Concerning the instruments, I really like them! If it were me, though, I would make them a bit wider and keep the vocals standing in the middle. Also, from what I've heard from an employee at a local music center, the mics that vocalists use are usually the best for harps. (I forget what they were called. Help me out here, someone!) But mic placement is key, he says. Keep it a good distance away with the mic pointing down. Hope he wasn't talking out of his ass!
And yeah, wtf NG. No folk option? Do we even have any country artists in this portal?
