If you look back a few paintings you will find the beginning of this painting.  My best paintings have to go through a transformation that takes time and guts.  It is difficult to go back into a painting that is just so, but not quite (if you know what I mean.)  I study a long time and then begin edit and add, just like an author telling a story.  It helps me to blog about this process, because it validates it for me.  It all becomes my Artist's Statement.
