Shape by Quentin Arnaud - Great examples of rim lighting. Bump up the ambient just a tad so the face isn't completely lost? play with reflectors to get a half lit nose/lips and some catch in the eyes? try with eyes closed as well.
Reflections and refractions in water, again, it is interesting that you can see the original and the reflected portrait in the same image, the white space between them is interesting. The Last Doll Standing: Work by the late David Seidner
The value in this photograph displays mostly a low-key category, mostly everything in this photograph is dark. But the value contrast is heavy, since out of all the dark shades, a slight light value of a hand is used to make this photograph pretty rad.
