Dahmage, your thoughts actually mirror some of my own, which is why I asked for some feedback before getting too far down this road. I’m also somewhat indifferent on the 3 lightsaber artwork, but thought as a minor graphic, on the back of a booklet stored inside the case, they could work.
The problem is finding a good graphic for all 3 movies that looks consistent and allows for laying text over practically the entire page (and the RotJ one has even more text than this one). I’ll also admit that while I usually have a pretty good eye for case layout, my graphic-editing abilities are fairly amateurish. If anyone has any ideas or can point me to some artwork for all 3 films that they think would work, I’d be all for it.
