Summer Glau looks great! 

My experience with faceshop is that it's almost impossible to not dent the top of the head in strange ways.  the morph that is produced is very basic, and relies heavily on the texture it generates to provide the likeness.  Strangely, this texture always looks GREAT in faceshop preview, but when loaded into poser, looks a lot less great. 

For some reason, even if the texture loads up great in poser, and you've spent six hours blending it with a base texture, it either looks "Hyper real" or totally washed out.  Hyper real is super saturated, unreal skin tones (and remember I'm talking about blending it with something you trust, so that it appears to be about the same.)

Following the standard faceshop scheme you can't get a morph you can use in poser.  You have to do it "manually" with an imported obj.  This means a LOT of guesswork and frustration.

The program is a good idea, and I believe it could be made workable, but it's a few versions shy of true functionality.
