How has the map visual design been improved in Counter-Strike 2?

You'll notice things in CS2 will be a lot brighter, as the entire lighting system has been overhauled, it adds softer ambient occlusion, more realistic light rays, and shadows to the environment that make everything look more natural. There's also a massive texture overhaul to every object, making you feel a little more immersed in the maps, without them feeling cluttered or "too pretty."
