It looks like the Fractalius world has been unleashed. I have one more to add. I used the Rounded filter, lightened the opacity and the fill, and then erased the effect from the birds heads.
Jim, I like the action in this image, as well as how the colors blend in the environment in the background. From what I have seen of Fractalius in this forum, I can tell you that I prefer the more subtle use of it. You have created almost a 3D effect-in the way the birds stand out from the BG.:)
James, Very nice effect. I like the Rounded filter and the softened stained glass look it creates. Some separation btwn ducks as Christopher noted would have been nice.
