Night Club - Character Faces

I have been working on the face designs for the characters in the Night Club scene ːsteamhappyː The character faces are generated and shaped with a base model that has facial blendshapes, this allows me to shape the face any way I like without having to lock the model down to one look. This does however cause a reduction in overall detail in the face (depth, wrinkles, etc.). I am still looking into a way to have overall better facial detail.
