This is a National Monument, Arlington National Cemetary, a Landmark, and there is an American Flag, on the right horizon. I like the photo very much, but, it does not qualify for this Challenge.
The fish-eye lens makes this a rather unusual image. The white sky was terrible - but you did really well to get rid of it the best you could. Title and subject definitely meet the freedom theme.
This would make more sense if the headstone showed a soldier who died in a war. I'm not saying thi man did not make sacrifices but the title and photograph imply the cost of freedom is sometimes death and this man obviously lived quite a long time after serving in those wars.
Photographically, it is a nice documentary photo of the cemetary.
