Looking good.  I do like the way it folds over - I'm also impressed with the alpha channel.  My feathers still have a white and gray fuz around the edges, like it is not taking out all the white.  I just used the image twice - instead of making an alpha channel in photoshop.

Not long ago I had a chance to investigate a bird wing from a little one that died hitting our window.  I wish I still had it to look at.

Never Give Up!
