Secondly, I don't know wtf is up with the shading on Cloud City. I know it's from one of the old mattes? But it's not a particularly good matte TBH. The way it is lit it would have to be... well, almost paper thin actually.

If you see here this matte has a lot better shading with a small but smooth transitional band from direct sunlight to ambient light, which is generally how round things shade when they are matte. And the shot should probably be updated to better reflect the circular nature of the beast.

You can take a taste of a more realistic shadowing and color grading as the sun moves in all directions :)
