I think i recognize some of the children.

Great shot!

it reminds me a little of Emilio Morenatti photographs, similar feeling here. Great capture.

i like this one. :)

Very cool image! The thing that really grabbed me here was the exposure. The lighting is so even and none of the windows blew out.

Other than that, those expressions are great. You really caught them "mugging" for this shot. Sweet!
