Thanks for the positive comments, I was kind of expecting a different response, but there's still some weekend left. 
Nick, I'm so happy Carl convinced me to add the reversing loops and to turn them so the trains for immediately use the crossovers to go to the outer rails if desired. I initially had no reversing loops and the crossovers were in the opposite directions.
Dave, I'm a fan of dog bones and reversing loops, mostly because I don't have to space for an around the room design with large curves. Even there though I'd still want reversing loops so trains can travel in any direction on all the tracks.
Ray, you have a fine layout and I can see the similarities in the design, though you have so much more space that I do. I love the multiple levels and how trains cross over each other. I also like the permanent winter scene, not many do that. My eventual craft room layout will be a 2-level permanent winter scene with a town (Bedford Falls) on the upper level and a desert scene on the lower level. Unfortunately, it will also be small, a 4x8x12 L designed mostly so my wife can finally display her Bedfords Falls collection. Thanks for sharing your video.
Bob, you never know, the space is actually 18'x19'. Given the layout will effectively be done in 3 sections, the section along the workbench could easily be moved away from the wall and over to allow for the addition of buildings, etc., along the back. Similarly, the section all the utility wall could also be moved away and out and all I'd have to do is reconfigure the angled section that connects the two. I have some scrap rigid foam pieces, so my goal this week is to cut a piece the size of the bottom loop to see how it's going to fit and how it's going to affect my use of the space for woodworking projects, etc.
