This is really great! Well done design, and has a very prestigious feeling to it, I especially like the first image. Although, it feels very empty, add more detail to it (I assume you are going to do that, but just wanted to point out out!
Add some people walking maybe, fill in the shops with stuff.
Thank you. a few years ago I played Paradise mall alot and made my own rip off game which was terrible lol It was called Paradise airport. It did not look good at all.
