Thanks, Gus. I knew someone would comment about the feet. These guys are so tough to get out in the open and the only one I got that exposed his body completely had his feet hidden by that stupid stick.
Ian, nice capture! If you have other RR images you might think about cloning those feet onto this one! You never know until you try!
I think your aperture choice was very good - you managed to get good detail from his beak to his tail - but they are so close to their environment in color and texture that it leaves him really blending into the BG. Did you try any blur on the BG to see if that would help pull him out a bit more? You might also try an omni spotlight (filter/render/lighting effects) to spotlight him and make the BG float away into darkness. Here I used both, applying the light first and the blur second and then sharpening the head and eye a bit more.
