While a glance suggests they are ok, they are a little dated.

Hi AleD :)

Thank you very much.

Some of your suggestions are, as you suspected, more appropriate for a dungeon scale style, but I will remember them ;)

There is a Frozen mud texture, which can be seen in the sample as that darker ring in the middle of the house ring. I can do a more muddy version of it perhaps?

I've updated the buildings so they look like this now. There's less bleaching, and more detail interest on both.

Ah, I see what prompted the suggestion now.

The test roof was a straightforward test of the texture intended as the background for the rest of the detail.

Here you can see the original ring of test house, along with a more advanced test (the larger building)

Remember that these are basically snowy versions of the Darklands City buildings, so the thatch houses will have a hint of the underlying thatch, and decorative herringbone near the ridge. The tiled houses will have a different pattern, where I have notcied that the snow tends to be thinner and melt first over the joins between the tiles. Other textures include working out where the snow will stick and where it won't on things like the arched metal dormers for the tile houses, and so on.

Maybe you could use the doors for shutters?
