I decided to go the "old photo" road with this.
I converted the image to a tritone using one of my sepia tones. I then added two render cloud overlays, one set to soft light blending mode at 100% and the other set to vivid light blending mode at 23% opacity. I then added a leaf texture from one of my photos set to overlay blending mode at 26% opacity, and a rock texture from another of my photos set to soft light blending mode at 42% opacity. On both the cloud and texture overlays, I masked out the bird. Finally, I added a vignette and a little noise.
Thanks for the play, Dave. Was a fun image to work with. :)
