Did the pregnancy mod get ahead with the art?
if you are referring to different bulging bellies for preg cycles evolution, it's not there the last time I checked, only the Inmon belly tattoo and cross section screen in the menu. don't get your hopes up, if this happen, we won't get the pictures before a long time, there's a lot of modifications to the originals, each and every one of Karryn's pictures have to be modified, multiples times, for the different stages of pregnancy, plus the tan/costumes variations.
It can be done, but it may be better to wait at least V1.00 to get all the game pictures. Plus, from the last dev post, I understood that a good portion of the art will be updated, so, one way or another, there will be a bit of wait.
