#1-camera is far too low, which makes her chin and lower jaw look excessively large and prominent. #2 has an optimal camera height, and she looks so much prettier in shot #2 than in #1. An accurate and pleasing size ratio between her forehead and her chin and jaw are shown in the second photo, and it really makes her look better. In the second shot, the camera is not looking up her nostrils, which is a plus.
One of the optical fundamentals in portraiture revolves around shooting the picture from a distance that is NOT too close. At close distances, even relatively minor camera height differences will overly exaggerate the size of whatever is closest to the camera, and will also overly "shrink" the size of things that are just a few inches more distant. This is what happened in the first photo--the camera is both too close, and too low, and it causes a fundamental exaggeration in the way she is rendered b y the camera's unflinching eye. She is a beautiful woman. A re-shoot is clearly in order!
My advice with today's high-megapixel d-slrs: never crop off the top of the head in head-and shoulders or bust-length compositions. On some extreme close-ups, it is permissible or even desirable to crop off the top of the head, but with todays's 16-,24-,and 36-MP cameras, it's almost always better to leave at least a few inches above the top of the head, for standard prints like 8x10, and also just for cropping flexibility and some leeway.
