Hmpf. I like at least. I agree that Thunderstorm might not be the best name, Sandstorm of something would be better.
Well.. Thanks for the comments at least. Much appreciated.

And by the way. What should there be more? If not brushes, it's the look that is important not what it is made of.
It wouldn't have that look if I deleted all the brushes.

Next one will be spaceart..
