Hello philc. I would say these are what I call street portraits rather than street photography as I understand it. These are nice portraits. I like the black woman because graphically/compositionally it is by far the strongest shot here as far as I can see. It IS a good shot. That old man with a hood and a backpack is an interesting subject, and you are not afraid to shoot in these situation, which is good. There is a lot of interesting, even weird people in the street, but it does not guarantee a good shot. The weak side of your photos for me is the fact that your subjects are isolated, they do not look a part of a particular scene or an interesting setting.
lets take the first one. The girl has some potential, her posture, expression .. If, let's say, it was a late night and that man in the frame was wearing a hoodie and just passing her there would be some interaction, a street scene. She would look nervous about strangers. Now it is just a young woman with one of her hands cut off. (Well, were it cut off by that guy it would be some shot. But it was cut off by you, so it does not count, it just does not look good in a portrait - and it IS a street portrait. ) I can say similar things about other shots. ( The bus driver is just a poor shot in my book, I do not understand it) Do not get me wrong, all your subjects are interesting, but you need to put them into some context - a street story, a juxtaposition, a graphical beauty - there are different ways dependig on your style. And you will need to decide what your style is. What attracts you most in scenes that you see in the street? It is not an easy question, but you have to answer it. Focus, toning, even composition is secondary to this answer.
Now I hope some big street guns will join and add to my 0.02 p
next time put numbers next to your photos , so it would be easier to refer to.
