That's very good.

Thank you!

Uppsala vibes

This is cool, it reminds me of a Viking Mead Hall or a Rohirric style build

Splendour

They are the Hearth and Home (tar) roofs. No mods at all, pure Vanilla (in creative) build. The white is due to location. Its at the base of a mountain biome and build tall enough to collect snow on the roof's highest points.

So question. What roofs are those? Do you have some sort of texture mod on?
