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?

Sadly, this style won't help whatsmyusename much either, since it is a city style, not a dungeon style. City symbols are not as detailed as dungeon symbols, so would probably be found inadequate for purpose.

I think whatsmyusename is perhaps unaware of the huge range of fills and symbols available through the third party packs, and that these can be imported quite easily and used in CC3.

EDIT: I have joined Reddit in order to be able to answer the question...

I've never heard of snow guards.

Maybe that's because I live in an area that experienced 6 inches of snow just the once in the 55 years of my life - back when I was 7 yrs old.

Thanks Jim :)

This won't be part of the style because there are a few things that need far more time than is available to sort out before March, but I'm also working on a night time theme that might appear in the more distant future.
