OK, on the second image, the eye is in focus. The third, the eyes are just outside of the focus plane. I think that in those two images, the AF sensor (which is larger than the indicator in the viewfinder shows) appears to have found the contrast boundary of the eyes.
I think that in the first image, the AF sensor again found the contrasty boundary between the shirt and the neck rather than the low-contrast boundary between the teeth and the mouth.
One suggestion - try activating the \"high precison\" spot AF points and see if the AF doesn\'t pinpoint the region/area on which you want more readily. While the \"normal\" mode is best for tracking and general photography, if you\'re attempting precise focus plane alignment, you will probably do better with the spot AF turned on.
