Building a Southern-French Castle/Palace in Minecraft

Hi, this might be an odd post on this subreddit but I thought it the best place to ask this

I’ve been working on a large Occitan-style castle-palace hybrid in my survival world and I’d really love some feedback or ideas to push it further. I started the design in a creative test world, but I'm now building it fully in survival. It's inspired by medieval southern France (Palais des Papes, Berbie palace Albi, palace of archbishops Narbonne)

This is just a rough sketch. I will add more texture and detail but before I start building it in survival I need your rating, opinion and advise on how to improve or deepen that occitan feel.
