tebop, may I make one suggestion, take it or leave it.

Figure out how to select your camera in the pull down. Look at the parameter dials. The first one is for focal length. For portrait work, the default of 55 is too "wide" according to many people, including real photographers. I use 150.

If you change it, you will have to reposition your camera, but you will avoid the unfortunate distortion called "fish eye" that comes with a human portrait up close with a focal length below 60 mm.

P.S. I echo mariner's suggestion above to learn from baginsbill about skin, as well as face off.
