Experimenting with idea

I like Blok's work as he uses really simple shapes and simple, block colouring - a perfect style to employ to a vector-based brief for people like me who have not had any experience with Illustrator, especially the pen tool before. Below are experiments that I did on Photoshop based on one of his work. I made a screenshot of Beijing and Honolulu on google maps and used the polygonal lasso tool to trace around and create a really quick and simplified shape of the city - I also cut and pasted the landmarks and things just to get an idea of where to put them:

not sure if any of these will look nice compositionally, unless landmarks are placed just anywhere (and not where they actually are in real life) to balance out the spaces in between them, to create a nicer composition because at the moment some of them are just crowding around a small area - does it matter if it's not accurate? 

I also had to change the orientation for Honolulu as it didn't look right in portrait format - if I want to make it work as a set, shouldn't they all be the same? Also not sure if background should be blue for Beijing - it makes it look like an island on its own when it's not. 

I tried to add in some more landmarks, but they're not
very accurate in terms of  their locations on the map.

here I decided to include the neighbouring cities to get an idea of what it'd look like if they had the rest of the land showing. At the moment, I'm not too fond with this - they don't look like they belong in a set anymore because the 3D appearance and the blue colour has been taken away from the Beijing one. And with the Honolulu one especially, it makes it look a little messy and it sort of removes the focus away from the city and the things in it because it feels like there is just so many things going on at once with the clashes of colour.
