They are a bit small so you can't judge by detail. I think they are okay as basic portraits, although I think with this subject, they would come out better with a smile. One thing to watch is small details. For example the necklace is not well positioned in the second photo, but just fine in the first. I would tend to want more depth of field to throw the background even further out of focus since it is a bit distracting. The second photo seems to have the model leaning a bit to the left which adds a certain unbalance to the shot. The whites look better in the first photo, so I'm not sure about your expousre on the second shot.
Here is a shot of Candace to illustrate one way of using the DOF to blow out the distracting background.
