(Request) Skin for Citadel of Minas Tirith Model

I made this model of the citadel of Minas Tirith but i can't find a skin that works with it. I've just started modding and i've tried to createa skin myself but it wasn't very good. I was wondering if someone could please help me by making a skin for it. I've included a copy of the model and some concept pictures in this post.

Maybe it is interesting to take a better look at the actual sizes and how Minas tirith really looks.

For texturing, base yourself on an existing "stone wall" texture and draw the stuff you need on that picture.

also take a close look to what these guys did :

Have fun

Its the citadel on top, not the entire city
