This is an excellent PJ image. He is alone and possibly prefers it that way. He is enjoying his meal in his own way. I like the composition and the leading line of his staff. My only issue is the tilt as seen in the background vertical lines and the horizontal top of the planter right behind the man.
comment: more a portrait than a street image because the background doesn't give info to contextualize the image and no interactions between people and background or between people are going on. That said, I love the details of the image and in particular how the man needs to be close to what he is watching...it is tender and moving. And his stick...it looks lot be a broom handle, which tells a thousand words about the conditions of this man.
