looks pretty out of focus. maybe would have reflected the title better if you'd take one of the pieces out of the middle row and not included it in the photo.
It's not missing (the piece).
It left because it didn't want to be embarrassed to be seen all mixed-up in such a disarray. Chess pieces are proud ya know - it's such an orderly game.
It's hard -if not impossible- to make a pleasant composition from things still in the box. I think you should have taken them out. That would also help the viewer to see there are only seven pons. Some of the whites are slightly blown in the picture and the whites have a blue cast, indicating that your WB is incorrect.
