Unity & Variety

This is my example of unity, everything is in place and the same size/shape. It doesn't feel like anything is missing in this picture.

Variety, being the opposite of unity, is represented by this picture. The sizes, shapes, and colors all vary.

Texture seems to be pattern zoomed in, an example would be:

Water from far away is a pattern.

The same pattern, just a little closer, looks more like texture.
