Counterweight is a collection of images, observations, and concepts by artist/creator Rick O'Brien.
I would consider the art featured in this book abstract. It might be a little hard to make form and physicality out of some pieces. In simple terms, it translate to,"Hey, nice art, but what is he painting?" For those that I can make out, they are about human characters and the environment.
He uses a lot of traditional medium such as egg tempera, oil, gouche, wood, ink, resin and plaster (for his scuptures).
It's very hard to review abstract. Everyone has their own interpretation. It's better for you to see it and decide for yourself.
