general comment..........background is lousy on all the shots....find a better location to work with PJ. The best Bokeh in the world can't help distractions like you have in these shots.
#1. nailed the eyes (though they could use a bit of brightening), but the DOF is just too shallow to make the picture interesting to me. With a full head shot like this I prefer to see the nose and the eyes in focus. The ears can drift out a bit. Fill flash would have helped a bit with this shot. It seems to me that the overall shot is a bit soft, maybe from too low a shutter speed?
#2 is a bit sharper and better DOF, but the ear is clipped and you are showing a bunch of what I call distractors (collar, background, very bright and colorful but OOF waving end of scarf). Crop the top and the bottom to focus on the head, I think it will help.
#3 has same problems as #2, though you saved the ear. This shot definately needed fill flash to equal out the exposure from the top of the head with the rest of the face.
