It is very difficult recording live, but to imitate a live performance I think is even harder. I don't know how to put this, but for me the atmosphere is not consistent. I like the live introduction, nice touch, but then it disappears. The middle bit sounds too "studio", not enough live atmosphere, it is a bit too clean.
You have picked a very difficult way to go on this one, and it puts a very good performance in an awkward position. I would either take out the audience bits, or involve them throughout the song and give the whole thing a live feeling.
That was my ears talking. The rest of me salutes a fine performance and a good steady beat, all in all a fine country barn dance type of track, way better than anything I could put up. Maybe a couple of Yahoo's and a bit of applause, or a chink of glasses. These type of gatherings tend to be noisy, full of hoots and hollers.
Best of luck in the contest.
