A couple suggestions. I don't know how good you are in your photo app, but you should clone over the teeth in the pic you're using. Also, the face room tends to generate its' textures a bit dark, so adjust to more European in the texture variation section. That is provided the hoped for character is white. :O) You might have to create a few textures before getting a good final result. So save the best effort in a folder elsewhere and use that. I clean out my textures/faceroom folder because I have so many rough drafts in there. If you're applying shape from the texture setup window, spin the caricature morph dial into the negative.
