The nice thing about oil paintings is that you can always go back and tweak them years later ifyou're not happy. I think this is possible if you varnish them too it's just a bit more labor intensive. I don't usually varnish a painting until I am very happy with it or it sells to someone on line. Then I like to make sure it is protected.
This painting was started in 2009 and now, five years later, I am going through my closet of "keep or burn"paintings and I rediscovered her. I decided she deserved one last chance before visiting the burn barrel.
