Looks fantastic.
- I originally thought that the symmetry inside would ruin it, but it actually looks fine because of the subject matter.
- you got the scale on everthing right, so it feels realistic. The space is nice.
- might consider lessening teh space between teh coutners and the standing shelves.
- The exterior looks just wonderful. I think you'll need to play with lighting though, make it early or late in the day. It will look too sterile in bright light
- The front checkout of the store could probably tell a story. Maybe look like a robbery occured. with some mess on the floor. That will counteract your eye's tendency to pattern on the structured layout, and remove the suspension of disbelief.
Really would enjoy trying it when you release it.
