Hi @duy-phan, glad that you found the inspiration you needed for your ARM proposal.
I think in order to make a concept more immersive, it’s always helpful to include a short paragraph that gives small details about the setting, the technologies they use, and the way people live in that time.
It’s just like video games nowadays, they usually also sell the novel or artbook as a parallel product, which helps enhancing the experience by immersing the gamer into its universe.
