Mature was inspired by the water lily petal shapes. It has rounded and soft curves, with one middle pizza slice shape missing.

Iape several times traced it and simplified it. Then I added the character's features on top of it, conducted the shape language test with the silhouettes, and selected one shape from the list. After that, I used the color wheel to choose the appropriate color and added some contrasts to the character. Finally, I finalized the shape and applied it to various designs, including tote bags, t-shirts, stickers, gif animation, and other merchandise.

 

Here's the image describing the process, from the beginning till the end.
