Incredible tone and detail.
I can see every grey hair on his head and every wrinkle on his hand and face.
Nicely done!
The only thing I don't like about it is the reflection in his glasses, but sometimes that can't be helped.
High scores from me :)

This is definitely a compelling portrait. I find myself very drawn in by this man's gaze, the detail in his fingernails, hair. It seems to be excessively sharpened - although the brittle quality of the line corresponds to his personality, it becomes distracting for me as I look at the image. The background is also super grainy, which doesn't work here for me.

Great shot! ... no need to say more.

This guy has an interesting look on his face :) Good b&w image.

This is a great shot, with great impact. But it has just a bit of blur that detracts from the shot.

Excellent - I might have preferred more space towards the left

Wonderful. The eyes are piercing.

Good one.

Hmm. Interesting character, but there's something odd about the image. It seems both slightly out-of-focus (camera shake?) and over-sharpened. Think about softening it. Good composition.
