I like these better. The problem with a dark face is that the attention is drawn away from the face. In the first on her arms really stand out. I like the second one better because she is separated from the background better making it easier to see her face. If she wants darker, more moody, pictures you might want to try a different location as well.
I am surprised that nobody has commented on her pose. Females are not usually posed with their shoulders square on to the camera but for some reason this seems to work in these pictures.
