rule of thirds

I thought that this leaf was a good example of the rule of thirds, since the main leaf in the picture catches your attention. Also, a side note is that the leaf is split into three sections. 

Even though there are many different background objects, the fire alarm captures my attention, since it is following the rule of thirds. 

I think this is a good idea for a portrait, since Amanda's face jumps out. My eye first goes to her face, and then to the other third where there is someone's reflection in the background. 

Even though there are lots of grids (bricks), the plugs stand out as forming their own line in the bottom third of the picture. 

The benches and windows create a grid of their own. 

This is another fire alarm. Both the white and the red jump out, and it is almost as though the white wall could be the aspect that is meant to be noticed.
