Progress: Painting #12 ( no longer a diptych)

Painting #12 has been sitting in my studio mocking me for the past few weeks. Taunting me with the possibility of what it could be. As a diptych the contrast between the two panels took away from the surface quality. I singled out the linear panel, flipped it upside down and went to town. Here's the result. We'll see where it goes from here.
