Some of the faces are quite nice imo, I'm not using one of the standard face.
Anyway... I'm not against more body modifications, I think it would be very nice to have them because of the diversity it would offer and if every premium guy would get himself a 12" cock I wouldn't really care since its not my real ass that needs to take those monsters.
The problem I see with bigger breasts and other modifications is that it will interfere with the current animations in the existing poses, they would have to redo lots of stuff to make it look good. I'm guessing that's why we're not getting any options like this.
