Military installations in Coruscant add massivness, while don't require much CGI, just the mattes. However, heavy rotoscoping tho.

I've been playing with that idea for a couple of days. If we make this scene happen in Coruscant, we basically are "free" (which isn't necesarly good) to do any other exterior shot in the Luke plot-line. Vader with the source of his power on his back (the Empire), while Luke looking in the distance to "civil" Coruscant could be a nice idea of what's going on there.

While I'm not a mock up expert like Angel, I find several things in the images that called my attention. One of them, the roundness of what should be straight lines, I left it in an independent image.

In the first pic, the perspective on the floor is weird and I had to touch it though didn't solve it fully. Fake plateau, forced perspective?

I mean by this that while I like the idea of the set, and I'd keep it, the built set has many things to correct if it enters an AE surgery room. So I'd rather Roto just the characters, which I guess it's less work compared to all the metalic triangles you had to roto out otherwise; and then make the rest on another stage (with straight railings, proper perscpective, etc).

Greetings!
