Just thinking of visual metaphors which could be explored in ROTJ.

One thing I really liked in ROTS was the repeated use of sunsets in the first half of the film, and the later use of night time to emphasise the fall of the republic.

Conversely in ROTJ, could there be a use of twilights and dawns to describe the opposite?

Which points could this be applied and where would it be feasable? There is potential for a sunrise during the sail barge assault, however this could be too early. Would the best point be just to end the film on a sun rise?
