Frank,
These two are more friendly and personal so I like them much better. Chantal seems to do better as a social person rather than as a figure model. In these two pictures she's fun and flirty. One can imagine them as being real and that adds to the allure.
The first two by contrast seem still and artificial and for these Chantal does not seem to be adapted well. Not that she did anything wrong, just that pictures 3 and 4 represent what she easily accomplishes and pulls off with no questions asked.
