Working in series can get very addictive :-). Not only did I start a series with trees, but as you can see from the pictures here, also one on abstracts:
As they are the first of a series, I have called them Composition 1 (black background) and Composition 2 (white background). Size is 12"x12". And as I recently joined Galleriba, they are for sale. Maybe an - early - idea for the coming December month?
