I am a children's fashion photographer but mostly shoot much younger children. This was part of a test shoot working with tweens (children who are not quite old enough to be out partying with their boyfriends and girlfriends, but not quite young enough to play with toys).
It's an interesting time for them. Both the boys and girls in these photos could get away sometimes with almost looking like adults or at the very least much older teenagers. It's only when they break out laughing, get embarrassed about making mistakes (that aren't even really mistakes) or nervous about hanging about on a frankly grubby looking council estate that you realise how young they really are. For all their confidence, they are still kids at heart.
