LOL at you guys, seriously This is an internet forum where anything more than a one line answer is a bonus. I'm not writing a thesis on the concept and application of DoF in today's multimedia. Some things are a given, or at least assumed to be, and the fundamentals of DoF calculation have been set in formulae for decades. It's true that they're not often spelled out, but as it happens, I have actually done that in this thread too (post #51). Then read all my posts, right from #22, and see who's making the mess here.
Del, maybe you need an eye test rather than a camera check. As I originally stated, the sharpest point in the OP image is most clearly visible around the guy's necklace and shirt collar, his sideburn and ear. That is about 80-100cm behind his eye, and a long way behind the guy on the left. It's seriously back-focused, as others have also stated. If you still think the eyes are on the sharpest plane of focus, then you have no need to worry about a little thing like DoF.
Edit: just to add to this, nothing is really as sharp as it should be because of the long 1/3sec exposure time. This has brought the ambient light level up high and allowed the significant and obvious movement blur to overlay and soften the sharp(er) flash image.
