You can watch videos on YouTube on this topic, if you have no inspiration, you can take ideas for building on the Internet (art, pictures, screenshots) for a variety of blocks can use color palettes (there are a lot of them on the Internet) to facilitate the process of building can use WorldEdit together with Axiom there are a lot of different functions, also eksperementiruyte with blocks and their variations, build on new versions there are more opportunities and blocks, I hope I helped you
