This document discusses key design principles including composition, balance, focal point, unity, contrast, and variety. It defines symmetrical, asymmetrical, and radial balance. Symmetrical balance occurs when both sides of a composition mirror each other. Asymmetrical designs have unequal sides that appear chaotic. Radial balance features elements arranged around a central point. Unity is the appearance of oneness where all parts work together cohesively. Variety provides diversity and movement while maintaining unity. Contrast uses differences between elements like light and dark.
