The Language of Abstraction

I'm taking a class at the Art Students League of Denver, "Exploring the Language of Abstraction" from Karen Roehl.  This is my first under painting layer using black ink, white and green acrylic paint.  I divided the canvas in half thinking I would make two paintings, but think I will make it one piece.  We are not supposed to do any more on it until next week, but I see where I can change things.  It only took me 15 minutes to do this step.
