First of all does it fit the challenge? Yes... definitely... and you did a nice job using grain in a good way, and not just adding it randomly, it looks nice and maybe gives her a more old time look... almost a dream.
Now on to specifics...
Compositionally this is very well done... I like the play between her and the book on her lap, and where they are placed, also the black and white works extremely well. The leading lines of her sweater lead you to her face which in turn her eyes lead you to her book and then back to the sweater... it keeps you in the image and is very nicely done.
I like your contrast here... very nice... but her blown out shirt really takes away from this image I think. you might wanted to have played with some light metering... maybe bracketing and see what came out of that.
I like your title... I think it goes well with the image, and what you were trying to do with the grain... this has a bit of an old french movie feel to me. How easy going and nice your candid is... everything works pretty well in this image... the only thing I really would have hoped for is better exposure for the shirt.
Nicely done, fun image... it makes me want to go see more of your work, and that's what I plan to do.
