That breathing animation alone looks like it was a giant pain in the ass to get right (the very slow and more subtle moves can be way harder than the obvious big motions, where each frame looks vastly different).
But ya nailed it. And the tempo of the breating motion, very satisfyingly matches the flapping of her coat and her bangs,
It's like the breathing goes in half notes (to put it in music terms). Going 1 (up).... 2 (down).... In one measure.
Then in the same measure the flapping of the coat and hair goes in quarter notes: 1,2,3,4 hitting the note each time at the most left point of the flapping motion.
Also took a long time to notice that it was actually 2 loops, by seeing the eyes blink once, then blink double the other time. Probably to make the gif a little longer, to let the stuff in the background to its thing.
That moving advertisement lady on the building looks really cool. But I love way more, that next to it, you got cars moving along the road. They are only 2 or 4 pixel-big rectangles, but without thinking, anybody can instantly see that its cars moving across.
