I think you should put the one with the circles and arrows into the critique section, it will give them a headstart.... that was sarcasm I'm sorry.
All in all I find them humorous. Of course the kid with the chicken is the best of the lot. It has a center of interest that is well defined and the crop isn't too bad. I think I would have shot it full length or cropped it higher. Full lenth to get all the chicken in or cropped higher to made it seem less clumsy but still it is a good shot.
This opinion is offered freely and it is worth every penny.
Ps is that a chicken sandwich in the girls hand on the roof.
