mono portraits John ( again )

William, I like this crop better. I also like John's pose and expression better here. It looks like he is inwardly smiling for some reason. IMO the shading is good as is the focus and DOF. I don't have experience shooting faces so don't know enough to give you any helpful tips.

A beautiful result again with very nice lighting, Bill!

I think the light is excellent.  I don't do portraits, but I'd give some thought to separating the rim of his glasses from his eye's iris.  The eyes are so important, I don't want to cover them in any way.  Maybe if the glasses were just pushed back and/or a very slightly lower position of the camera.

I agree about the crop and light  Bill, and this one has us seeing a bit of mischief in John's eyes and expression. I think I'd like him!

Beautiful portrait, great light!

That's a cool photo my friend! The communication between the photographer and the model worked fine, congrats!

really very good portrait

Nice, I like this one better than the other one, the light is interesting and the pose/expression and angle is great.

I think B&W portraits of men is really your strong suit.  Not to diminish your other offerings but I like these best.  The lighting is simple but effective and the monotone presentation is classic.  Sharpness throughout doesn't hurt either.  Excellent character study.  Looks like someone I'd enjoy having a beer with.  Best, Len.
