I do a lot of street photography and that image is a good catch. As Kodiak stated he is a candidate for discussion. He has a well worn face that tells a story that I would like to know. He looks very much like my brother who is an alcoholic.
He looks too clean to be on the street. Does he work? Has he a family? His eyes tell it all and then of course there is the nose and blood spots. That face has a great story to tell. If it makes the viewer ask these questions then your work has been well done.
You have also respected the person by not making disparaging comments, unfortunately others have done that for you. This is where street photography goes wrong. Excellent shot, unfortunately some not so excellent comment.
