Neverending story....

Sorry these are terrible pictures. Laptop camera is junk. This is a large painting I have been working on for a long time off and on. I keep feeling like there is something too generic about it. I have some metallic paints on it. Paint pen is used on it as well. I know some of that is lost. Feel free to make any suggestion no matter how wild... I'm a little stuck. (Also, the colors are much more vibrant in person.) Thanks in advance!
