Wow! So different for you. I hope you gave her a copy of this. I know you used to work for National Geographic, and this could easily belong in its pages.
Just a terrific portrait, with the light, shadows slanting across her face, and the excellent light in her eyes. Really a nice job. Let her know, if you would, that some folks on 365 think that she is a wonderful portrait subject. :)
Bold choice to throw a beautiful lady's face into shadow stripes... but inspired. This just works on every level - and so different from your normal work - Fav!
