On the discover page you can choose which character you want to be from cinderella and then snapchat puts the item that represents the character on your head. There will also be a little henry in the corner of the page to show that he is always there for you.I used animation on snapchat to make it more fun and childish like henry as a brand.
I think if i had the chance to develop my work I would create more characters for henry and think about what other edits you could have to show the cinderella concept. To have henry interact with you I could think about artificial intelligence and henry will move around the image depending on what you are doing. It could also use your location to show the environment around you to make it look like either a ball or the part before cinderella becomes a princess.
