The cropped photo illustrates lines and a view point rule of composition because it shows that repetition has a massive impact on the composition. So the effect is that it has a message that the photo conveys.
My Review Based on what I've been reading, existing T2i users will recognize the shape and feel of this camera, as it's an almost identical design. The T3i is slightly bigger and heavier, and it has a much better hand grip than its predecessor. Unfortunately, because of the camera's articulated screen, the 4-way controller is somewhat smaller. But the T3i is another sturdy and well-built camera that will give its users years of pleasure.
