Yep, I've also found that when my DD does modelling jobs she also becomes more quiet and reserved than what she is usually (her normal character is quite outgoing and she rarely is quiet!). She's normally never shy but especially at the beginning (when she started doing catalogue modelling at age 7) she was a little hard to "warm up" to the job. Now she is used to the staff (especially at Huge Studios for Target jobs) and isn't reserved but still isn't as outgoing as she is at school. Modelling has been good for my DD because she kinda needed to calm down a little and learn to follow instructions (which she's done well because of her work)... but i agree, if a child is naturally reserved in her comfort zones of home and school then i would think twice about modelling because it does generally make the most outgoing child a little anxious at times.
