Honestly, try not to have it so similiar to Jailbreak. I didn’t even have to read the description, I noticed the first image right away and knew instantly it was something similar copied off Jailbreak. Try and expand your imagination and make something new and interesting.
Instead of taking their ideas and re-creating a different style to what the stores look like, you could try expanding and adding more to the game but also taking reference:
Jewelry store > you could create a lab, large mansion, or artwork store instead.
Car store > this could be adjusted in your home garage, instead.
Recommend adding some more shape to the build and maybe some modern stuff such as an overhang, The Pronto-Stop is a bit bland and plain and just has no shape at all, maybe adding more depth and creativity to the build would make it stand out more.
Police Base has no windows and maybe add a sort of helipad on the roof with a staircase outside to get up. Also experiment with other colours to see what you like best and something the players will see and be attracted to.
