What you shot is the middle of the fair.....If you shot the set up, the city setting barricades, vendors setting up etc.
at the end people picking up trash you would have a complete story.....
as for pictures, some are light, some are dark, cropping is an issue...missing body parts
on flickr you talk about colorful costume yet you shot in B&W, You say it's a peace event looks like halloween in the castro district. it doesn't say peace to me.....yes I know its the nutty people of sf...but you will have a hard time with an essay with your pictures....turn it into nuts of sf then you got a story.... If you had the occupy movement instead you could sell it as peace event...
So if God made Man & Woman....whats his excuse for Nikon...
