Thanks to everyone who posted comments, they are valuable, exactly the kind of feedback I've been looking for and have given me some great ideas to work with. And I knew you folks would point me in the right direction.

Probably the common thing and the most often posted comment refers to "Audience Interaction" I pretty much have sat at the keyboard played the gig and have not interacted the the listners other than briefly acknowleding their applause.

As far as singing, I have been thinking about some lessons, looks like I may start taking some.
