Astonishing dynamic effects, and a remarkable image quality. Then again, I would expect no less from the D1x...:)
Very well captured, using the fill flash on the rear curtain.... The playful effects of the light sure are amazing.
If only the woman in front hadn't been playing with you. In all fairness, not the most charming look, and although expressive and joyful, I think it does reduce the technical quality of the photo, reducing it to a very good shot for those who know the woman. Being a complete ignorant bystander, it's nothing more than a woman sticking out her tongue. If she had the same joyful expression as the girl next to her, I think you would've struck gold. Not intending to be blunt, just describing my thoughts.
