Well, I'd naturally be biased towards Sumeru's architectural styles, wouldn't I? I think of all of them, the classical stone and tile look is probably my favorite...artisans can produce such beautifully intricate designs in the tile work, and the blues and greens that are common in the natural pigments of the country compliment the jungle well. The white granite pops nicely, and is quite durable.

But that isn't to say the styles out in the desert aren't also beautiful...or the style used in Ghandarva Ville, where they largely grow and shape their buildings around the natural forms of trees.

[G'raha what have you done.]

If we're talking about other countries...well, Liyue's buildings are austere and elegant, and the dark woods they favor in construction create a sense of dignity for even smaller houses. Liyue is rich in all kinds of minerals and woods, so they're spoiled for choice when it comes to how the accent their buildings. Fontaine in contrast uses white iron and marble in almost all of the city, and it glows brightly in the sunlight, especially as it reflects off the waters. It can honestly be a little overwhelming, especially on sunny days, and I....do wonder who was responsible for the layout of the city itself, but there is no denying it has a powerful first impression. You should ask Lyney more about it, especially the Opera Epiclese, I'm sure as a performer he knows all kinds of things about the building.
