Cedric: I like shots 3 and 4 the best. 3 is Breughelish in its simple celebration of people in a public place, and 4 is ominous, as if something shady (no pun intended) is going on.
One and two seem to be too random in their concerns. My guess is what you saw is not what you got, finally, and that if you'd been a little closer you'd have got it.
Regards,
Doug
