Hi there! This topic may get moved but great to hear you've taken the plunge and looking at your current MOC it looks like you have a nice 'classic' style. By this I mean that it reminds me of the classic lego castle sets from when I was young, so how about looking at them for inspiration? There are plenty of ideas for carts and shops if you are interested in creating a more peaceful atmosphere.
I also think the recent Mill raid set is a good example of how you could introduce low level conflict into the outer regions of your build.
A builder that I really enjoy (but as far as I know, doesn't post on this website) is this guy http://mocpages.com/folder.php/142239
who makes castle MOCs reminiscent of the classic sets. There is something nostalgic in the simplicity of his builds. But even in this case, simplicity takes a lot of effort!
I hope you enjoy the new baby, and you'll either have no time at all, or time late at night to design all your MOCs while trying to get the baby to sleep!
Less talking, more MOCing.
