I have been coming to Eurobricks for years, but until today I've never felt the need to have an account. Today this thread changed that. This is the most beautiful set of creations I've ever seen. Have you thought about submitting it on Lego Ideas? I would buy every single one. The ring is beautifully built, and I'm wondering how exactly you pulled it off. The sets within the rings are extremely impressive, yet simple enough that they could be marketed successfully. Honestly this needs to be submitted. Well done.
In terms of suggestions, I would love to see a Death Star Trench run, as mentioned previously. I also think that Dagobah (centered around Yoda's hut), the Jedi High Council Chamber, and a beneath-ground view of the Lars Homestead would all fit into this idea wonderfully.
