I agree, it leaves something to be desired in terms of sharpness - but I still think it fits my description: it was as good as it could have been for the great master to manage to capture it just exactly like that. And I do NOT see the exploitation of the subject by the photographer at all. Sure, there are not musts - let me rephrase it then: I do not enjoy images that cross those boundries. For me then, its a must have. And I would say that it is my personal stance on it that photographers should NEVER exploit.
You do what you will.
