I love how you used the light in all of these shots, including the OCF in the last two. Just makes her pop beautifully against the natural light bg. I think fill light could have helped with her dark hair in 1 and 2, but may have taken away from the natural look you got there.
I am curious, though, why you shot at 10,000 ISO when you were shooting at 1/800. Why not shoot at a slower shutter speed and bring the ISO down?
I shot for about 8 hours the entire day (company headshots + product + scenes) prior to shooting Rachel. With a lens like the 200/2 handheld (a tripod/monopod would've had me kicked out), it's hard to get a sharp shot even at 1/250 and VR in the dark, especially if I'm 40-50 feet away taking a full-body shot. I usually set to 1/500 with VR or faster when shooting at night, as I found that shooting any slower kills the keeper rate of photos by about 70-80% (more blur). I upped it to 1/800 because I knew I was tiring a bit. And I definitely don't mind the grain or loss of DR.
The 200/2 has a few different rules because of it's weight and sharpness (just blows the 70-200/2.8 VR II out of the water at 200mm).
Hope that all makes sense.
