As said, these faces are NOT default replacers; they actually appear in CAS/Bodyshop in addition to the existing defaults (or the default replacers). So effectively, you will have more than the standard 27 faces available to create your sims from.
1. I mentioned Argon as the creator, because the original tutorial was his. As for the faces, Arathea is, of course, the real artist
2. The Wanda archetype (see the picture) is based off the sim that I published a picture of in Fish Pics; she was my creation. Arathea converted her into an archetype for me.
3. Some more pictures may be added later...
