Symmetry

This is not a photo of symmetry. The clouds are not symmetrical. This is a bad example of symmetry.

 If it was just a clear sky and a rainbow in the middle it would have been a photo of symmetry. 

Framing

I like this photo because the crutches frame the person in the background. The light on the crutches make them shine so the color of them sticks out more, and makes the frame more noticeable. F-stop 10.0 Shutter speed 1/200 and ISO 100
