Stuck in the Drawing

There is a thing that happens to me (I'm sure it happens to other painters, too) when I begin working on an WIP.  I get stuck in the drawing.  The fluidity of the under painting is lost when the paint dries. I suppose this particular painting has an ambiguous ending, as I don't have any clear idea where it will end up. I enjoy the process of finding my way, usually.  Right now I'm frustrated. My plan is to scrape back some of the layers so only a ghost will show in certain areas, then work back on top. 

Progress thus far.
