A few things needed to make a powerpoint suitable for an adult audience

Ok, this is the redesigned second slide of my "AIS Afterschool clubs" presentation. It was redesigned into what I thought was suitable for an adult audience. Well, what are a few things needed to change a powerpoint so it's suitable for an adult audience? The size of the text, add pictures instead of cartoons, the background.

Making the text smaller will make your powerpoint look more professional. Adults read newspapers, and newspapers have a lot tiny words, right? Making the text smaller could allow you to add more text.

Most adults like to see pictures instead of cartoons. So add pictures will probably catch some adults' attention so they could pay attention to your presentation.

The background cannot be two colorful. It would be good if you're using white as your background for any of your powerpoints for adults. Making the background not very colorful will make your powerpoint look professional and suitable for adults.

These are just some of the few things needed to make a powerpoint suitable for an adult audience, so try to find more things that you need to change to make a powerpoint suitable for adults.
