I do like the large bird in the foreground pushing everything else into the background. The letter C which is background but looks like it is being eaten by the bird or at least is in the bird's mouth also works. I am working on some more ATCs for the Facebook group I am in and as I do I am noticing all the work that is put in on the background. Much of it is covered up with other ephemera. That is the name of the collage game though.
