I think that tharget audience is for children because there are kids involved in the commercial only, I would say that target audience could be on teenagers too because they would find that halerious and fun to watch. It is for both genders since there is a boy and a girl in the video. 

The location of this commercial is in photographers place because you can see the lightning and camera in the set. The small girls dress is purple, it links to the Cadbury Chocolate’s  package colour. Both kids are sitting on the chair waiting for the man to come back and take the picture. The commercial is very light, you can tell it’s a day time, plus they have lightning directed on them so it seems even more lighter.

In the first part of the commercial you see two kids sitting on the chairs carelessly and bored, you can tell that by their body language (long shot). Since  in the commercial their eyebrows move to the rhythm of the melody, they use close up to their face. The melody sounds like a phone ringtone ( the guy in the first scene got a phone call) it is fast and playful, like a online game.

I think this commercial is very silly, but it has humour in it and is fun to watch. I would give the target age from 6-15.
