This image incorporates many different aspects of form. The first thing I noticed was the simplicity of the image, how it has very little to distract you, bringing your focus to the arrows. The three arrows being the same shows repetition, and almost a pattern, with each being at 90-degree intervals. The blue arrow on the left makes an otherwise almost-symmetrical design into an assymetrical one. The emphasis is definitely on the arrows rather than the text, because of the scale of size difference between them.
