That looks pretty sweet alright. I'm quite surprised on how well you managed to clean the image for hi-res. Quality-wise it looks even better than the ESB one, I think.
And for the blokes trying to create something to go along with AvP's bobba fett cover: in my opinion the trick is to find a single icon that is able to symbolize the whole movie without expressing any action directly. My suggestion for ROTJ would be a vector conversion/redesign of this:
The green lightsaber (although here it looks more it's blue). Is easily one of the most recognizable elements of ROTJ. Not only is the weapon of the Jedi, with the colour that symbolizes hope, it also brings us back to that magic moment when Luke activates his new lightsaber for the 1st time (and more recently to the missing lightsaber construction scene). It's simple, easy-to-understand, and carries a whole lotta meaning.
