Pick cute or fierce before designing
A baby shark style works for greetings and love reactions, while a fierce shark works for victory, no, focus, and competitive chat replies.
Make the silhouette obvious
The fin, tail, and mouth shape should read instantly. Avoid ocean scenes that make the shark too small inside the sticker.
Use captions that fit the theme
Bite, nope, on my way, hungry, focus, and big mood can all work if the expression supports the phrase.
