The RO3 is just a guideline...and, by my way of looking at it, one of her eyes falls right on a rule of thirds intersection...and both eyes are on the top "RO3" line... but beside that, there are other things at work in this shot as well. For example, she is seated...We can actually now SEE that,and I mean in the shot we can literally see that she is sitting on a step or stoop or landing...she has her little hands at the bottom of the frame, and her legs and arms kind of lead the eye upward and to her face. Her face is brighter than the dark doorway and the brickwork, so her face "advances", since "light advances and dark recedes," as the old saying goes. her legs, and hands, and arms are creating what is called a "base" for the portrait; in the very first shot, she was a "floating head", with no torso...not to sound mean, but...that's what landscape orientation DOES on a close-in shot many times...it deprives the person of a "base"...the head is just "there"...
I tried to crop this roughly the way it would look if shot with a 3:2 aspect ratio camera...not measured precisely, but just my quick "guess" as a normal 3:2 frame aspect ratio. it might be a few millimeters too tall, or too narrow, but I was just trying to make a crop that simulated the way *I* would approach framing this shot with a normal d-slr that captures 3:2.
