Hey @Puddinroy! I LOVE the architecture of Lunar Lakes! When it comes to making over a town, it takes me a really long time. If I can't decide on something, I leave the project alone and go on to something different. I'll return later with fresh ideas.
I often take a break from building and decorating to play some random challenge. I really like @SamelaRita 's renovation challenges where the family is dysfunctional and/or destitute. You play until the youngest child is an adult, making over the home as they get money. They aren't allowed regular jobs and must scavenge, paint, write, etc. for income.
Slumps are actually a good thing. They get us out of our comfort zone and steer us into unchartered territory that offers many possibilities. I hope you find some great adventures ahead and then return with fresh ideas for your make-over.
