pushinfaders,  so far all suggestions are for postwork.  I see no techinical issues of the photo in the first place to criticise and will offer a possible postwork addition.

To me, the true tense nature of the shooters face is important.  This is his shot.  I did a very quickie selection and brought his face a bit.  Perhaps this works, perhaps being darker is better.  Look and see what you think.  Oh, I edited once more and brought the "assistant's" face down a tad, even if not evident now posted. : )

Still, the focus was limited by shooting conditions thereby limiting dof.  That is part of the circumstance.  The shooters face is there as a prime and nicely focused part of visual impact.

So much for my ability at this...a look see at my thoughts.       Tom.
