You see here again, whilst there are a lot of blown highlights, the subject herself is exposed just about right, meaning the lighting of the scene is too unbalanced for the portrait. The pose is much more appealing though.
Generally, light coming from one direction should fall onto the model's face rather than the side or top of her head, or any other way that would blunt textures and contrast on the important parts of the portrait - the face and upper torso.
Taking yourself through a strobist tutorial like lighting 101 and 102 would give you an idea of what works in these types of portraits. You certainly have a photogenic subject to shoot, so keep working on it and enjoy the process!
