I want to make a Skyhold Model

since most reference pictures I find online are with the female elf inquisitor, I use her estimated size of 5'2" or 158cms. calling the estimates EFS or elf female size. the thick wall by Cullen is the first part I am measuring, to try and get everything worked out. the path way is about 2 1/2 efs and the height of the outer wall is almost exactly 1 efs.
using that I plan to measure out the size of the walls by how many of the path can fit into it, with the efs as a smaller measurement (like feet and inches, but wall path and elf female heights lol)
once I get the outer wall I can work on heights of the walls, the size of buildings and doors, and than work into the details. it's a lot of work but once I finish it'll be awesome.
