I liked this one the best -- it happens to be the first frame I shot:
I was hoping I wouldn't overexpose too much the fur in front of her ear. I played around with different color and black-and-white presets in Lightroom just to see what I'd get, but I ultimately left it in color and just added a bit of fill to bring out the shadow details. A vignette was also added to make you look at her.
(Shot with the Nikon D300 using the 50mm lens; aperture-priority, with aperture set at f/4; camera chose shutter speed of 1/160 second; auto white balance; ISO 200; normal JPG.)
