For most of us, friends and families are what really matters. Do your characters think the same? Are they closer to their friends than their families? What is the role of the family in the society you've created?
What is the role of faith in your created world? (I would hope, being a Christian, that portrayals of religious people would, yes, show up the hypocrite etc but also show those who really do try to follow the faith with love and kindness etc etc).
What really matters to you as the writer with regard to the story? What are you hoping to convey by it? Why does it matter and can you use that to help you write it with more passion than you might otherwise have done?
