The main thing that stands out is the flower necklace; it is pretty obviously maniped onto there. I would redraw over it in your cartoony style to get it to match. Other than that, I think you could use a bit more muscle definition.

Design wise, maybe something that makes the element sections more interesting, like starfish on the water section and clouds on the air section.

Overall, I really like this thing! It's cute.
