What I think is fashionating in Wind is it's strength. It can break big trees as if it are matches. But wind can also be very gentle, give a little breeze in the leaves , whispering.

In my work I tried to combinate the two of these things: gently and softly moving details against the strong and firm base. I hope you can understand what I"m trying to say. If not, please ask for more text, than I"ll try to explain better.
