As for the shadowing then there are 2 light sources as has been mentioned before. if there was just one coming from the bottom then the shadowing on the original would be wrong. The shadow in NormanS version is almost correct but the shadow is way too long.
The shot of the falcon entering hyperspace after the TIE battle was changed at the last minute. i decided we didn't need to see it going to hyperspace because Vader informs us straight after anyway. i just haven't got around to changing it in the list
