Howdy David,
Well, you've certainly nailed the country genre quite well
You do a lot of things to capture that feel, and I agree that the guitar is one of the most difficult instruments to reproduce with anything other than a live one. Of course players of other instruments will also say the same of their particular instrument, I'm sure
I really liked how you used the bass drum for the "heartbeat" section of "Heaven" - I'm sure that could be made quite effective in your live theatre situation. And I also enjoyed the fiddle part - it does weave in and out with the lyrics quite well.
I'll confess to being a sucker for bass walking lines. I have a good Hammond B3 soundfont that I used for the third number you put up, and that along with the walking bass made it really fun musically.
Thanks for sharing some more of your work - it's always fun to listen to what other folks are doing, and to help get musical ideas going
ttfn,
Sherry
