It's a funny place, japan by julianna wang

The story of this illustration talks about how the main character (Julianna Wang) though about what japan would be like and how she explores it when going on her trip there. I though this illustration was really nice and i would like to do a little of something similar to this talking about london just that instead of telling it into as if i was a tourist which i am not i will just set out my journey in london with the things i can do in my spare time.
Looking at it again i don't think the fact that there is only one colour used ruins the book, infact i think that is what makes it stand out even more.
