Greg,
I have read a few different comments (one by user AndroiD), that point to your LH and RH being out of sync according to precise tempo. Other members have pointed to this as intentional and part of the Free Hands motif.
Outside of that, I don't think anyone has been able to be critical of your work effectively.
As to the Skype, when I can consistently set the time aside, I do know your rates are *completely* reasonable.
