This work is mainly abstract in nature. A large, light-colored form with softly-curving edges occupies the lower half of the canvas. It is a light blue-green color; however, a yellowish-white area fills the upper-central portion of the form. A green form resembling a leafy tree occupies the middle ground, while a dark blue mountain-like form fills the background.
