This is heart rendering. I am a genealogist and find myself often in graveyards, documenting and writing about graves. This one speaks to me. Love the patch of red too.
I really feel the selective saturation on this image hurt you one this one. It's way to saturated, the flag is too small and centered in the frame for that to be effective.
This picture works with or without the flag, and would possibly work better with the flag being toned like the rest of the image. While the subject matter is still, and at rest, the flag interrupts that tranquility with its bright, red color.
