I don't think I understand THX's comments about the logos because in Trooperman's versions, "Dark Side" is clearly bigger than "Shroud".
As for the stacked "of the" being different than Jedi-- that's a good thing! All the OT logos were unique. This one should also have quirks if it is to truly fit.
"Return of the Jedi" is a very solid concept which is easily conveyed by those words. "Shroud of the Dark Side" is a poetic and vague phrase that has no concrete imagery at all. So the layout of the words has to help convey the meaning-- taking emphasis off "OF THE" makes it just a little easier to grasp what the title means.
Just my thoughts, anyway.
