So Millinaire style housing and systems? Yes, can be done in one shot without just copying and pasting. Certainly.
If anything, desert villages should forgo wood quite a bit, with stairs rather than ladders, meaning you can walk everywhere in that kind of village. Maybe a nice palace or temple instead of a chapel for the priests.
Now all we need are tundra villages made of snow blocks. That will be neat. As for now, at least the houses are more fitting to their surroundings. Birch wood and plank villages randomly generating alongside normal villages in prairie biomes would also be awesome.
Gotta say, I'm a bit disappointed in the desert villages too.
The #1 rule for good-looking structures is don't build it all out of 1 material. There is way too much sandstone going on here, which makes things like the fences on the huts, and the stone slabs on the blacksmith look horribly out of place.
I think Jeb should've left some cobble, and maybe even some logs in the buildings. They're way too plain, and look like a modest gust of wind would level the village like a sand castle.
