Creating an Abstract

Creating an abstract is a difficult genre. It needs balance, composition, and all the components of any great work of art regardless of genre. I thought I would go though a few steps in creating one of my pieces.

This is the beginning of a piece. I’m really just playing by creating marks and using a water bottle.

In this image, I’ve stated editing by removing shapes I’m not happy with and keeping those that work for me.
I’m continuing the editing process.
And finally I reach a stage I’m happy with. How do I know I’m finished. Because adding or subtracting will not improve upon what I have.
