That's beautiful. I love the sign and rooftop details, and the lighting came out really nice. Have you ever tried Liquid PSA on downspouts? I use it on them whenever I attach them. You don't have to worry about any wet glue squeezing out. But yours came out fine, so I should shut up. LOL
PSA is a great idea - I hadn't even considered it. I'm currently working on a structure from Downtown Deco (Classic American Block), so I'll give it a try when I'm attaching the final details. Thanks!
