My initial idea

Happy foundations is a company that want to promote happiness

Since posting this I have decided to change the story a little. I have decided to no longer follow the story of the 2 siblings as it limits me to focus on only these to individuals spreading the smile instead of multiple different people so instead I am going to show someone smile at the camera and the whip pan to a different person coming into color and smiling. This way I can have many people from the school smile and keep everyone safe as I would mainly need only one person to shoot at a time making this experience easier for me and better for the advert.
