Really neat layout. Like others have said, the backdrop alone is great. It's also very clean and open without the large number of buildings and cars and everything else most of us would've tried to cram on there. By keeping it so open, it really creates a larger feel to it.
Is the yellow and brown building in the distance O scale? It almost looks like you tried to force perspective by going smaller in the distance?
Thanks for sharing this and if you have to end up tearing it down, hopefully you can spend a lot of time enjoying it while you can.
