It has now become easier than before to throw together a map and post it online. But to create a truly exceptional experience, you have to pay attention to the details. As a result, I have now began using custom resource packs in my map, including custom textures and 3D models. This helps change the mood, or feeling, of a world, and has the power to make a build look dark and grim, or vibrant and bright. 

Most importantly, however, are the builds themselves. By incorporating diagonal structures, curves, and other organic shapes, as well as building at least some interiors, builds can feel more natural and realistic.
