This Ad that I created as an update from the previous one (shown above) is a prime example of center alignment, contrast, proximity, and repetition. Between the bright yellow and the vibrant blue background, contrast is shown. The way the model is shown on the poster on the right shows center alignment. Especially since your eyes are drawn from the top text and shift downwards towards the model in the center. Proximity is also shown with the two rows of the bolded titles that are grouped together. Last but not least, repetition is prevalent in the way the yellow of the garments on the model repeats in the designs on the background.
