Principles of Art

The first image show balance because all the pipes are lined up and are black on the wall.
The second image shows harmony because the hands and sleeves are the same.
The third image shows movement because the subject is in motion.
The forth image shows variety because there are multiple colors and focus points.
The fifth image shows contrast because on the left there is a pink alive flower and on the right there is a dark brown dead flower.
The sixth image shows unity because there is a reddish poles only in the image.
The seventh shows rhythm because it is the same step over and they are the same.
The eighth image shows emphasis because the different barrels and the different objects make a statement and pop in the image.
The ninth image shows proportion because they are almost the same but one has no lid.
