At the moment there's no preview picture but I'll make one tomorrow - I'm in the process of moving everything to word press because I think a story / chapter format would be nicer than just a bunch of pictures. It's basically just edited EA stuff though. The mod just replaces the default animation of the "Happy" state so that instead of smiling they look more neutral. It doesn't affect animations at all so if they tell jokes they laugh and smile. If you wanna change the emotions themselves I'd suggest the gloomy trait as well, I know a few of my handmaids will have them.
