3 You’ve got to feel something first
Art transmits emotion. The best design is the one that communicates the most powerful experience. If you want the viewer to feel something, you have to feel it first. That feeling will transmit to the viewer like a rubber ball bouncing off a wall. The harder you throw it, the harder it'll bounce. Likewise, the more you feel the idea, the more the viewer will, too. As Howard Pyle recommended, project yourself into the picture. Leap through the frame and live inside the picture.
