That is a great image, I am sure the subject would be more than pleased with this.
You have captured the pose and expression perfectly.
The only thing I notice is that it is cropped a tiny bit bit too much at the left side (as you look at it), needs just a little bit more space there IMO………/Mikka
It is a great sharp shot, nice detail in the face especially. I think it is a bit too tightly cropped overall though. In my opinion, the armor the man is (most likely) wearing might give it an extra good impression. Well done though!
Too much contrast in the B&W version, the face is too dark and highlights are blown out. I tried to process it different way, hereĀ“s my result:
The first photo is almost perfect, however one eye seems to be a bit out of focus (f/8 was probably not enough for 200mm lens). But in general I like it.
