Disclaimer: The following are the thoughts of a raw beginner!
I like all the stuff you shoot Joe, but I don't really feel experienced enough to critique, but I'll have a go...your b&w images especially, are always great, composition is always good. You have interesting content but I feel you could work on the context in which it is portrayed.
For example, if in the third pic, if she was looking straight at you it would of drawn me in more and made it a more interesting shot for me. Something like the pic you took of the girl behind the flower stall, giving you the 'look'. A bit of confrontation makes it interesting for me.
In the last shot, I feel you could have moved more to the left, close in, portrait orientation, concentrating on framing eyes, coffee, phone and the nikon. It would have made for a busy shot like there's 'stuff' happening...a bit of urgency about it.
So in summary I'd like to see you get in closer and to stir things up now and again...(very easy for me to say sitting at my keyboard.) But in saying that, if I took any of the shots above with my r-d1, I'd be very happy.
