doesn't exactly feel like wind but more like something metallic, looks cool anyway, but doesn't achieve what it is intended to.

Not really depicting an air/wind crystal.
I suggest you to add some keywords in the description, for a wider usage of the icon.

Looks like a dark crystal element.
It's not your best icon but, isn't bad.

Well, in his defense I have to say that depicting a Crystal (which is basically an earth element) as an Air element isn't that easy, especially because wind is invisible.
