only kinda know of nichijou because of a meme (good morning evernyan! Oh my gah!) but so far I’m really digging this. I don’t get the connection tho??

That's Azumanga Daioh, hence the confusion. If you look up something that's actually from Nichijou the resemblance is obvious.

The art style is really cool and I was kinda shocked because I’ve never seen anime try to emulate depth of field like this before.

I think it's probably the simplistic character designs that make it possible for the animators to go above and beyond with their cinematography. Simplistic character designs, talent, and hard work.
