@CannonJunior I agree, as with the dragon, I think the Stonehearth-Style is to design all models in a similar size and to simply re-size them later on. At the moment I am also struggeling to get a feeling for the right style, but we will get there slowly.
Maybe you want to give it a try and see if what I did with my last model also works for you. I would be interested in the outcome, as I did not try it yet with a more complex structure like you have them. I have postet a short guide to the procedure, if you are interested.
