Old school style japanese convenient store!

I am currently working on an old school themed build since I wanted to go for the same aesthetic as the image below:

The image above is Times of change by finwei

I’ve just started the build and I was wondering if I could get any feedback.
Anyways, here is the build:

Time spent: 1hr 13min
Part count: 1380+ parts
Status: WIP


The overall style and shape of the building is great, the colour palette is especially good! however I think the walls would look a lot better without the stud marks on them, it looks counterproductive.
