Dan, You have done an excellent job with the paper models and your own photo-backdrop!! Your 3 dimensional scenery is starting to look great as well! I used the same metal brackets for my Ceiling Central RR as you are using for your Marceline upper level.
I hope you get enough working to give your great-nephew some enjoyment next week! Right now, I'm liking Marceline as a handy shelf for tools and supplies. I put in shelves underneath my layout for that purpose. Who knows; if we ever have grandchildren, I may end up having a Thomas train or some other running on the low shelves for the children.
