Flyer for children activity center/ Public speaking programme

I need a flyer designed to advertise a children activity center and public speaking programme, specifically targeting elementary school-aged children (ages 6-12). The main message the flyer should convey is the idea of fun and social interaction. I do have specific design ideas in mind, although I am open to any creative suggestions that may help to make the flyer stand out. The purpose of this flyer is to capture the attention of the target audience and inspire them to take part in our programme. Rough concept is attached here..
