#6 bothers me... If I was eating in public and a stranger took a picture of me with my face stuffed (and then put it on the internet!), I would be mortified.
But street photography is interesting in its own way. These seem like pretty good candid shots. Why do you like street photography so much, out of curiosity?
i would of liked to see them better composed, maybe not people in the dead center of the frame. put them off to the side and get a little more of the scene in view. just my opinion
