That's a lot of lights, I'm glad I'm not paying that light bill.
Looks really good, gj.
Speaking of lights though.... the lights look really thick, I'd suggest making them so only one rivet is shown. And, even though you have nice even lighting, it might make the map look cooler if you experiment with some area lights instead of the consistent lighting layout. Just a couple of quick thoughts which I saw. Lookin good though.
