This is an abstract of a tree/the human mind/the universe. Take your pick, or think of something new. I'm always welcome to criticism, but abstract art tends to be difficult to criticize, simple because any critique would be about the merit of the idea, and not the image itself. You can find my other images at my deviant art!
My drawings don't have color unless I choose to Photoshop it into the image later. It's preference, nothing more than that.
