Answer 1

they say that this world is beautiful. saying that her face is a map of this world is the best complement a girl can get.

Answer 2

i think it means her face is really complicated, hard to read. like, the whole world you can't just scan with one gaze, she is the same

Answer 3

I don't know what it means, but the second artist is KT Tunstall

Answer 4

i think it means all the places she's been and the people she has known and the worldliness of her is written all over her face.
