Hi Anna,
Another great portrait , much deeper than what your D3 can go. You got a mix of a smile and an pain expression.Smile for being subject of a picture from a nice lady, curiosity why nice lady did fancy to portrait her, looking at herself and the enormous distance between her hard working life and the nice lady with an expensive camera. Curiosity, may be, to discover the other world took notice of her. We´ll never know her thoughts , I guess you did not chat with her, I´m only wondering , when I do a portrait in same circumstances and have the chance to chat with the subject of my shot, very often there are genuine curiosity what they have of interest to justify a picture.
Ciao
