Still early in the game, but post-apocalyptic repopulating humanity theme has been there for such a long time that I'm surprised no one has made it yet. I like Winterlook's other work, so paying close attention here.
Not sure if he checks this at all, but the father's art is a little feminine. Though he doesn't have a chest, his pose is the same as the females, and his face looks like a woman put on glue-on facial hair. Not enough to prevent enjoyment of the game, but it could be better. As he doesn't have too many different poses, it shouldn't be too much work to tweak.
