Great mockup!

I love it. The original one looks so bland.

I am also for adding in the planet Endor is a sanctuary moon for. Like you have in this pic.

I don`t think it is feasible for adding in wookies. I think we are stuck with the EWOKS. But you must admit. Ewoks are better than gungans. EWOKS are way less silly and idiotic.

I would prefer the end battle between Vader and Luke on Coruscant... I just don`t know how you would do it. Seems you would need to change diologue to make it make sense. The end battle in one revision was supposed to happen below coruscant in a lava room.

I can understand though, that Lucas and Kasdan moved it so that it puts Luke in peril and connected to the events of the large space battle.

Matticon.
