I never really liked how the stone upgrades clashed with the rest of the buildings,  so I set out to make them prettier, while still keeping the vanilla aesthetic (also I'm not a pixel wizard). The biggest obstacle was the top of the buildings, which needed to be identifiable as stone fortifications. I'm still a bit iffy about the towers' roofs, tell me what you think.

The mod exists in two variations: light grey (picture) and limestone (picture).
