One of the strong points of this set is the background/subject separation, done in different ways in different shots.
In #2, for example, we see f16 to keep the background sharp and a big part of the shot, yet with contrasting colours, she stands out so well. Then in #3, a nearly blown out background keeps her the dark part of a bright frame and again she's the subject that stands out.
I could go on, but I think the point is made. So many other have problems making the subject leap off the background and become the center of interest.
