This is gloriously insane! Your integration of actual sets with your own creations is flawless. I am gobsmacked at how completely immersive this layout is. Improvements? I think not. This is a dream come true and perfect in every way. Play on!
Now that's awesome, a huge city! Not unlike what i am planning once i get enough space to set it up. Some very cool buildings and vehicles of your own design. Looks like it has been fun to set up all those very nice scenes too :-)
