This document discusses six design principles for combining visual elements: pattern/repetition, contrast, proportion, alignment, balance, and movement. It defines each principle and provides an example image to illustrate it. The principles are pattern/repetition of recurring elements, contrast through differences in values, size, color or shape, proportion relating to relative sizes of elements, alignment along lines, balance with symmetrical or asymmetrical arrangements, and movement through implied or literal representations. Unity occurs when all elements support the overall theme rather than distracting the viewer.
