I imagine Garlemald mostly like a cyberpunk like city rather than a modern city in real world.
Tall metallic buildings with intimidating look. Robots everywhere to serve and fix/build things.
Everywhere smoke and pillars of cerulium smoke everywhere. No temples of any kind anywhere as Garleans forbid any form of religion.
You will see a lot of workshops though. Small and big. They live a military life. Their society is structured just like the army ranks.
I expect to see monuments of emperors/generals or past great scientists in the streets though. Perhaps some museums of Magitek history.
Dark skies and very cold. Garlemald is built on a very harsh and cold area. Worse than Ishgard.
Magitek helped them survive and establish their nation. They had it very tough when they went there.
Don't expect to see a colorful happy city. The land there is dark and harsh.
