The lines in this photo almost create a grid line of their own, the black keys are the main focus and they are on the top line of the grid.

Your attention isn't drawn to the middle of this photo because of the way the objects lay.

 I believe the rust catches your eyes more than the scenery at the end, the rust happens to take up half of the picture which would make it land on two intersecting lines.





It's clear what the main object is in this photo, and since I used the rule of thirds by placing it to the left of the photo instead of the middle.

This photograph tends to draw your eyes towards the left, as well as all along the top.

 

The focus in this photo is the handle, and the light reflecting off of the cup. The reflections land mostly on the intersecting lines, as does the handle.

This photo draws attention to the perimeter of the photo, which balances it out by the rule of thirds.

This photo consist of the rule of thirds, the nail is what draws your eye it's off the center.

I used the rule of thirds by creating intersecting lines, &taking it at an angle so that your eyes arn't just staring at the center.
