The Rule of space: Using a lot of space in the image gives the sense of movement and thought in the image.
These images are examples of how the rule of space can give an impression of movement. In the image on the left, there is not much empty space around the subject in the image. However, by adding a lot more empty space in front of the subject, as shown in the image on the right, it gives the impression of movement, as it looks like the subject is moving into the empty space in front of them.
