Don, This was mostly a trial of David Young's suggestion for better 
noise control at higher ISO.  Since there aren't any areas of deep 
shadows in this picture I don't think this was an adequate test of the 
technique; with this in mind I don't see any significant noise 
artifacts in this picture.
