Noir / Chiaroscuro lighting

Tonight I felt like trying some noir lighting study. I won't deny that noir photography, or chiaroscuro painting is one of my favorites. I really want to learn more about it and get better. I could use your insight on what should I focus on in terms of shadows.
I would also like to see some of your art with this theme. Doesn't have to be black and white pics.
Here is a little Bonnie and Clyde, or Miranda and Lucas if you prefer.

Keep rendering folks!
