This Dragon Stack painting is about to slip through my fingers, so I have to do a lot of back tracking ie., redo the impasto underpainting in some parts and reglaze over that. Acrylics will allow for that. Anyways it's the background that's causing the problems. The dragon herself is fine.
I can almost control this glazing process, but not quite. If it turns out a "failure" I will have learned a lot.
