Hmm, I think I see what you're saying.
When Leia says "you came in That thing? You're braver than I thought.."
our heroes were in a corridor that was parallel to the hangar, on the same level as the control room (which is on the angled wall section), so the angle for that scene should be more like this?
I think you may be right, and I never thought of it before.
This image is right above 3P0, at the same height I've put the windows to the control room (a measurement I based on the camera angle for the shot that's in the movie.)
I've started a real render to see how that would look.
As for the Yavin exterior, I did build a rough model based on the shot you posted, but descided to go back and do a model based on the original matte painting, which is quite different. I agree, though, that it would be really cool to see the falcon outside there.
Shaunsheep, I've also started you're render, showing where Vader and Old Ben had their duel. This time with a bonus: I've added some stormtroopers into the mix (downloaded from the sketchup warehouse)
Thanks all!
