The audience my film is going to be aimed at

My film is going to be mostly aimed at the ages 12+ the reason why this is, is because there is not going to be any swearing in my opening film and it isn't going to be too violent or scary. The idea that I have chosen to do is a crime type drama with a mysterious twist, where three kids firstly play hide and seek and are having a normal average day then something terrible happens after a while when one girl discovers the body. The reason why I chose this idea is because I can easily portray different camera movements to make it look as realistic as possible and the overall outcome will also look very professional. In addition the audience that I have aimed this at is mostly young children who can enjoy it a lot more and understand it a lot better than adults, also using this idea of a crime type scene makes it more interesting and when the kids are playing hide and seek at the beginning the audience thinks everything is okay. But because of the title this gives the audience an enigma code towards something unexpected that will happen near the end and I think the type of audience I have chosen is the right one for this type of film from the ideas that I have discussed above.
