Kanga and kakada's visit during golden week @Akashi bridge

There were eight members included me in today trip to Akashi bridge.

However, in the photo at the first rank is only contained four JDS scholars and a mother of Kakada.

Do you think that the second and the third pics reflect the latest photo's style or the popular style among the young people in 2009?

Can you tell what these two pairs of the second and third photos are trying to show?

Hope, without a precise description sharing here, you all could make the effort of these two pairs visible..la la
