Regarding the spider shot, for those distracted by it, may i suggest as an alternative to what i mentioned about moving fog around etc.. maybe a slow zoom in.tracking shot towards the ships direction? (if the original source image is clear enough)

regarding the engine talk, i noticed this.. see image mock up..

As its still being discussed, i wonder if my post may have been missed regarding the perspective/ vanishing points. I personally believe the shot filmed was correct in the beginning with no engine removed to film R2. Maybe a wide angle lens was used? if you follow the green line on the right, look at the panel line behind R2 on the deck of the ship. it follows the green line, as do the windows follow the lines on the right. the red hoops are where i'd assume the engine fronts would have been on the ship. actually, i should have but the right hoop a tad lower, as the shot of the xwing is not dead on side view or we wouldn't see the top of the deck at all. Though, i do think Adys addition of the engine looks aesthetically pleasing. Thats my 2 cents.
