That’s the kind of creative burst I love to see. Keep the chaos in check by building in small, reusable pieces—prefabs that you can copy and tweak instead of drawing everything from scratch. Lock the parts you’re happy with, then iterate on the new layer on top. Use a clear hierarchy so you know exactly what’s going where, and test a bit at a time before the whole city starts to sprout on its own. If you keep the base simple and only add detail as you lock each section, the model stays manageable and the magic stays under control.
