At first sight i didnt know but i had a feeling something was different on her.
Now i know that her ice wings are bigger, does that mean shes older in this pic?

It's... This...

It's beautiful.

The ice she created with the spell card she used is falling slowly like snowflakes... Shining gently to the light of the moon, taking over the whole scenery to its own.

I'm speechless! This is truly beautiful!

“Isn't it beautiful? Isn't it? I did not know ice could be this pretty since Letty showed it to me once! It's been our secret ever since!”

“...It's beautiful, Cirno! T-This is amazing...!”

“It's a secret, OK? So don't spread around to other people, OK?”

Is it a secret that light actually reflects on snow like this?

Well, might as well roll with it.

“Of course! I promise I'll keep my mouth shut.”

Oh, such a radiant, pure smile!

Canon wise, Cirno seems to have large ice wings, at least from my understanding.
