This is somewhat documentary in nature and could benefit from better time of day with more diffuse lighting and also using a different perspective to give a better sense of repetition to the grave markers than you have shown here. Perhaps focusing in on one marker and showing a line of them fading into the distance using a shallow depth of field to make them out of focus.
This is a very busy shot, with lots to look at. Nice focus. Nice added splotches of color (flag, Irish, cross). Lighting is difficult, but handled well.
