Another tiny point: the nose lights on the Executor from 0:54 to 0:58 are green (as opposed to the blue of the rest of the lights on the side)... just wondering if the lights will be blue across the entire side in all of the Executor shots...

The lights at the tip of the Executor have always been a different colour to the main lights. In the original they were an orange colour to match the stardestroyers lights, but in the 2004 version their colouring became green. The shot of the executor leaving the asteroid field hasn't had anything done to it yet, but the lights will be recoloured to match all the other shots of the executor, although they will be more of a cyan colour and not changed to match the other lights as i really like the difference in the tip lights.
