Well, I am not wild about the grass wallpaper of Vista. And I like the other two, so two out of three. And I was thinking about the suggestion by another person that you might make a transparent version without any image. Of course there is energy and the aurora wallpapers in Vista, as well. No pressure, of course, they are yours to make or not.
Yes, there is some transparency - it's just not what I was anticipating when I looked at the preview.
I thought you were showing us 1 icon, displayed on various backgrounds.
I'm not criticizing your work - only saying it wasn't what I thought it was.
