Social Media Ad Creation for AI character App

Need a simple 25 - 30 second ad for my AI Character app's main character Sarah. The ad starts by Sarah speaking up a little about herself and then some pics/clips of her, ending with the App's outro stating "Talk to Sarah, *Exclusively on Bezu AI*" (We are already having an outro). The ad should look professional and bring good user engagement to the app, attracting users to talk to Sarah.

We are open to ideas for modification of the script, the goal is to create a really impactful/influential ad.

Please provide samples of your previous work.
