Hey Keith;
I'm sort of typing as I listen....Good piano sample (what did you use??) and nicely played. Most listeners' ears would not tell the difference, but I think a real one would sound better.
Nice voice - well tuned and nice quality, though it is often drowned out by the instrumentation. Bring it forward in the mix. I like the harmonies too.
Acoustic bass sounded good and was effective for this arrangement and instrumentation.
Instruments were well mixed throughout (though vocals need to be more forward).
The jazz bit sounded nice w/horns and stuff, but seems totally out of place musically, as far as "fitting in" with the rest of the song.
I'm surprised that your last work (though I didn't hear it) only got one star. I'd certainly give this more.... just a bit of tinkering is all it really needs, IMHO.
Chris
