I like #2 and #3. #3 was a nice use of a horizontal portrait.
#1 though....eh, i just cant make myself like it.
you obviously made that bokeh the top priority in the shot, and I get it...some people like that sort of thing.
however, you have sacrificed pretty much everything else that makes a portrait good in order to get it. focus, subject detail, decent DOF...
it doesnt even look like she has hair in that shot...its just her face coming out of some blackness on the side of the frame.
the wavy bokeh lines at the top and the squiggly bokeh light mess at the bottom are very distracting.
if that is simply "how the lens renders subjects", then personally speaking, i would not be using that lens for portraits.
I feel #3 is the strongest of the set. i like the pose, her expression, the color...my only nitpic here is not enough DOF for me. i dont like that one arm is in focus and the other arm is not.
