You have some beautiful portraits of this woman but there are a couple things that bother me. First, why are you shooting at 1/4 second?? That is waaaaaay too slow. Are you using a flash at all? If not, then you might find some extra lights to bring in and use them creatively to help. Strobist.com is a great place to learn about lighting techniques without getting into high dollar equipment.
Next I will ask, why is the colour temperature so green? The subject is beautiful, but the colouring is just detracting from the look. Get some editing software that can handle changing the colour temp in a photo, or find the settings in the camera. Most new cameras, even point-n-shoots, will have a setting for the type of light being used. Play with those and find the one that works best.
