I think for me the quick answer is I like the idea/play here but feel you could have set it up a little better.

Firstly the 'fallen king' is the subject so it should be obvious in that role. I'd suggest turning the king so we can see his cross.

I'd also choose a DOF that isolates the king more from the background pieces and keeps the king sharp or at least his cross sharp.

Thirdly I'd try to arrange the background pieces in a way that leads the eye back to the fallen king. Make sure you do that in a believable way though ... we don't want to upset Iguanasan again by not having the choreographing correct

Another 'leading line' suggestion might be to take the shot on an angle that uses the chess board lines to lead us to the King also.
