I'm with Robert (as is typical), only real problem with the shot is the positioning of the head. Everything else staying the same, this would be really compelling of the foreground head was set on the right-third.
I really like this photo too....except for the head. It has a sense of mystery, like the ladies are dressd up and waiting to go somewhere. Pretty nice flawed image!
The only "flaw I see here is that the foreground head is eclipsing the background figures :-) The grain is good, the focus is where I'd want it to be :-) In fact, it's a pretty cool picture if we could just move that head...
