Okay, I happen to like banjo music (and, really, all sorts of Blue Grass), and I like this.
A couple of things I noticed: At first listen, it sounded like the banjo was lagging slightly behind the beat. Then I realized that you were "double picking" (I don't know what it's called) the strings for the melody line. To my ear, at least, the second pick was dominant which contributed to the feeling that the banjo was lagging. When I listened closely, I realized it wasn't -- it was just the particular technique you were using. Take it for what it's worth.
Also, is the instrument in the background a steel guitar played with a bottle slide? Whatever it is, I think it's fine for the well-placed accent, but it got a little tiresome all the way through. You've got the banjo playing both the melody line and rhythm, the bass playing bass, and the steel guitar playing accents. I think I would have liked to hear another instrument -- maybe a traditional guitar or mandolin -- providing the rhythm and a little more variation in the banjo lead to give it some build. Maybe a modulation the second time through?
Recording-wise, it sounds good to my ear, nice and clean.
Nitpicking aside, though, I liked it and look forward to hearing more.
