using 2 landmarks to convey chosen cities

i thought i would create more landmarks for each city to try and create s stronger representation. though this meant i would have to spend a long time creating more detailed vectors i thought it would make the postcards more visually interning and not just show the predictable one landmark the city is known for. 

Beijing - forbidden city and cctv building.

London- big ben and the London eye 

Sydney - sydney opera house and the harbour bridge. 

paris- Eiffel tower and arc de triomphe 

if i was to choose the landmarks differently i would perhaps use one highly recognisable landmark of the chosen city and pair this up with a less well know building to add curiosity and interest.
