Thanks you very much, Jeanine and Elizabeth. Sorry for the late reply. I was swamped at work.
I really appreciate the points both of you have made. This painting was done almost 4 years ago. It bugs me everytime we go over to their place and seeing the flaws. But some of the flaws you pointed out will really help to make better.
I will ask them if I could take the painting home and do the retouches. Thanks again.
