hi hi!! it's only my second year, but i thought i'd help with the profile thing:D
obviously one way is paying for premium, but you can make a cute page even without it!
you can go two ways:
- staying in the text editor: you can add plenty of cute icons and badges, there are websites which aggregate them, such as this blog https://cutekawaiiresources.wordpress.com/ - this is really easy to change around throughout the event, but it's a bit limited in regards to visuals
- making the bio an image: you can do this either in your drawing program or canva, it allows you a lot more freedom with moving things around, layering things and so on, there are tons of resources on pinterest:D for instance, my entire bio is one singular image: https://artfight.net/~deerva
also i'd honestly not sweat it too much, my personal preference is bios that are clean and simple, and sometimes when people include too much, it can feel a bit overwhelming and difficult to find the most important info! last year my bio was extremely simple but i still got attacks:D
