I made this to improve my production modeling workflows and to practice getting noiseless partially-lit interior scenes.
It's mostly done in Blender and Zbrush. Some UVs and baked maps, but much detail ended up coming straight from the decimated Zbrush sculpts, w/ polypaint imported as vert color and used as albedo (most roughness was procedural or custom vert paint)
This little composition is actually taken from the amazing physical work of this scale-model builder I found on Pinterest. Check out his other miniatures, they're great!

Miniatures builders tend to develop really different kinds of beauty than CG art does-- I'm guessing its that the material/workspace costs results in lots of love being packed into smaller-scaled scenes. Instead sprawling ancient cityscapes like King's Landing, she might come up with a gorgeous alleyway or a really funky house/shop/watchtower. I think I'll do more CG based on these!
