I've noticed there is no "Rebelliousness" in the thread. Is it actually gone? Because either Rebelliousness or Obedience should go - they are basically the same stat in different directions.
I am pretty sure Rebelliousness is derived from Obedience, Spirit, Traits, and maybe some other things, not entirely sure about that though, feels like is has been years since that came up the last time.
I agree that Looks is a too simple way to look at things, and Beauty really is a redundant stat since there seems no instance of an ugly girl in the image packs (who would want to include something like that in their game?). But your Body stat is not much better, at least when my interpretation of it is right.
I would prefer to see Body as a variable calculated per customer - people have different tastes and not everybody likes Tits that are larger than the head of the person they are attached to.
There are actually beginnings of a system for how much a customer likes a specific girl - sadly in customer satisfaction, so after he has already chosen (I am not sure if there is something similar in the choosing thing. I think there is only a flat looks/horniness check though.)
I don't think Speech/persuasion is needed though - I would continue using charisma and let it mean all the verbal and nonverbal little things that make a girl look attractive without her being a looker.
Although that can be a wide spectrum of different things similar to a girls personalty, for example a silent Ice Queen, that just moves in a way that pulls the eyes toward her, or the chatty flirtatious girl that makes the customers head spin with things that can be understood in more than one way.
I think the game would profit from having a clear definition with examples for each stat, but I guess this is what aevojoey is basically doing here.
