I think your element is air.

Can I say "Spring?"
No?
How about "Flowers?"

Ummm.

You really look like the fairy of spring blossoms.

Element, though... I guess flowers would be Earth element?

You are most definitely earth.

You're definitely a water element.

I guess today I'll go for a "light" element to reflect how in Spring, the sunlight hours are getting longer...

I still think you are earth, but you could also be air.

Ummmmmm

I want to say either "water" or "sound" and since I don't think "sound" counts as an element, that leaves "water".

But that's so unimaginative...

Still.

You really have a lovely water-themed avatar, so let's just acknowledge it!

You are ALL of the elements. Because that's what the rainbow element is.

As it can be dark at the bottom of the ocean I think your element is darkness.

Unbeknownst to most, but darkness is your element. Just because you can be bright and cheerful doesn't mean your heart can be full of darkness.
