Promiscuous girl

This is one of the very few times when I can see that (perhaps) black and white is better than colour. You have emphasised the girls hair and eyes in a particularly striking way. There is a bit of yin and yang going on with the shape of her black hair and the white garment (you might need to have a feverish imagination to see that but I think it's there to some extent, intended or not).

Far from being promiscuous I think the girl, though stunningly attractive, is being slightly shy. But perhaps this is a contradictory feminine wile which serves to inflame our male passion even more strongly (in a yin and yang sort of a way).

The focus on the girl is so strong that I tend not to notice the background consciously. But the background does give the photo extra impact - having strong, "chaotic" lines that contrast with the calm poise of the girl.
