I would have to say the same as Carl, but then again I find 99% of the street shots posted here (and elsewhere -- not to pick on Pentax Forums!) to be completely boring. It's not that I cannot like "street", I just think it takes a lot more patience than people give it. In fact, I would guess that if I shot for eight hours I'd get one or two good shots, where the moment really gells. Or maybe I'd need to shoot for eight days.
Ask yourself what you are trying to achieve. Are you attempting a pure document? Is it to capture relationships of space and form? Is it to find incongruities, humour? Is it an anthropological study of the human animal? Is it to find cute chicks with tight jeans?
This to me is just random people mostly out of the prime area of interest in the frame, doing random things.
But that mark on the ground is interesting. I would have made that the highlight, maybe got down on my knees to shoot along and up it at whoever happened to come into frame.
(I wouldn't do that in this city, mind you, or I'd be in trouble.)
Hope this somehow helps. If you are interested in this sort of discussion maybe the thread
For Illusion Isn't The Opposite Of Reality would be useful to you.
