I personally like this black and white photo very much (the one taken on Feb, 5th)because it looks very spontaneaous, the woman's smile is sincere, not fake, even though this woman doesn't have the 'perfect' Hollywood smile (her teeth are very bad in fact) but the sincerity and simplicity behind it makes it all the more beautiful. Her whole face (her eyes, cheeks) is smiling too. On the contrary, the cute little boy seems to be hypnotized by the camera, that he looks at very fixedly and the contrast between them is interesting. Good picture, very moving in fact, congrats!
