I am so happy to see the updates with your pack as I already purchased Modern Interiors and was very glad I could snag the early bird for this pack! Everything looks so amazing so far!
If you're looking for ideas, perhaps a subway or railway? Public transit is always a fun part of the city! Or perhaps some street food or vender stalls... even a farmers market!
So many options, but regardless of what you do or do not include I know it will all be amazing. Keep up the good work and best of luck, I'm cheering you on!
