When to Sign a Painting?

 

                               

I've always loved the challenge of painting the human figure, but these paintings always seem to need more work.  With a still life or a landscape, the point at which I'm comfortable with adding a signature is often clear.       As I downloaded these photos from my camera, I could see so much that needed to be fixed.  For these two paintings, the deadline of an art festival next weekend is my only incentive to sign and frame.  If someone loves them and buys them as they are, I will be very happy, but next week they will probably be taken out of the frame and tweaked a bit.  I'm fortunately meeting with a group of fellow artists tonight for "critique night."  I'm sure my list of fixes will be enhanced after their insights
