Plates layered on top of each other with simple lights lighting up the racers car in the middle, which is boxed off in a triangle by black cable. Oh yeah, and there are LEGO Racers panels adorning the back wall.
I guess the complaint I'm trying to list is that therre's basically nothing to this. It isn't even an original car on display to help pad it out. It's really, really barebones and seems very much slapped together, even more so when you didn't even bother to cover up the light bricks from the back, which end up looking brighter than the floodlights.
Overall, yeah. I know it's gonna get disassembled and repurposed for other things, but if you were hypothetically going to keep it around, I'd really recommend working on it.
