So I built my own Cloud City this month... here's the results:




Copied my explanation from the otheR Site:
So the biggest difference is that I'm using Light Bluish Gray and Dark Bluish Gray instead of Light and Dark Gray. The little control panel on top of the carbon freeze chamber needed to stay Dark Gray since it doesn't exist in a Bluish form.
I also (as the earlier posts explain) didn't have a good way to make the large round corners that should be light gray. So, mine are made up of a handful of pieces that only came in Dark Bluish Gray (not enough things were available in Light Bluish Gray to do this). They are held together on the bottom by black plates that you can't see and work pretty well.
There are two 2x4 wedges on the end of the little platform where Luke loses his hand that should be Light Bluish Gray but don't come in that color, so I went with Dark Bluish Gray.
Overall, I'm very happy with this given that it was considerably less expensive and looks pretty strong. If I come up with a better way to do light corners at some point in the future, I'll switch to those.
Next step is figures... I'm going to go as cheap as I can... a custom (or older version of Fett)... then I'll populate it with some Stormies, Threepio, R2, grab an extra Lobot, etc... and then I'll tackle the Leia, Luke, Han, and Lando whenever I can find reasonable deals.
Also, it bugs me that the back left corner (near the window) isn't closed in... don't know why they did that, but I might look for some way to connect those two walls at some point.
So, yeah, I'd love to hear comments or ideas or criticisms or whatever. If anyone has any figures that would go well in this thing they want to part with at reasonable prices, let me know. I'm going to start shopping on eBay and Bricklink this afternoon.
