Very nicely played. I particularly like the 2nd harmonica part.
I play this tune also, you can hear my version at tonyeyers.com Just click the player at the top of the page.
The next step (you may have already done this) is to get a working bluegrass repertoire, around 20 tunes or so. Then you can join in with bluegrass jams, assuming that they exist in your area. Bluegrass players are receptive to harmonicas if you know the tunes.
Nicely played in single-note style (you can also gussy it up with splits, slaps, and so forth but first you need the tune, and you've got that nicely).
One technical point that may seem small but could get big as you develop speed while trying to maintain solid rhythm: When you go from one draw note to another in a neighboring hole (same is true for neighboring blow notes, too), it's easy to go too fast because this is the easiest move on harmonica. Making sure that you're staying in time with the beat or its subdivisions. One tune that's really great for working on that is Soldier's Joy.
I definitely second Winslow's advice here. I still have trouble getting this seemingly simple move perfectly even, Soldiers Joy is the tune to get it with ---------- Tony Eyers Australia www.HarmonicaAcademy.com everyone plays...
