Couldn't agree more.wonderful detail.'There is no point pressing the shutter unless you are making some caustic comment on the incongruities of life. That is what photography is all about. It is the only reason for doing it.'......Philip Jones Griffiths
I like the composition and subject. Personally i am not a fan of this highly sharpened style though there are a few masters of this image processing that can accomplish very moody portraits. I think the area leading up to the ear needs to be treated also as it creates a rather unnatural line on the side of the face. Still a very interesting subject. Looking forward to seeing more.
Truly love the colors and subject matter. You really should get him to pose for you again. One comment: on his right cheek, some of the area looks a bit soft (considering how sharp the area just above it is) as though it has been cloned over (and there is no stubble there). Point is, you have a great photo and need to camouflage any noticeable post-processing. Again, I like it a lot.
