I'm all for a few subtle references to the prequels, I mentioned the neckless earlier but I'm not too keen on flashbacks unless it's in a Godfather 2 type saga re-edit where they can be a meatier.
I would love to add a few whispers to the cave sequence in ESB (I mentioned giving the lizards and snakes a few subliminal connections to fallen Sith Lords, red and black markings, sith eyes etc, it is a dreamscape so you can get away with a bit of trickery there).
The odd Clone War era ship in the fleet of ROTJ would be welcome too, all those weapons would have to go somewhere (either to a wreckers yard or sold on on the black market) and that works both ways I'd love to see OT ships in pristine condition in PT too.
Outside of Ady's ANH:R I'd like to see the family graveyard put into the Lars homestead and the readout lights from AOTC's Garage being put into the ANH garage.
Nothing as stand out obvious as sticking Hayden's head onto Seb Shaw's neck but little touches that people who look for them can notice (like having the battledroid in the Sandcrawler in ANH:R).
On a seperate subject I've searched high and low and not managed to find a good isolated shot of the Endor deflector dish at night (without a ship or building in front of it) if anyone has or finds one I would be very grateful if you could send it to me in PM.
The last mockup I did is mostly Angel's work (I just added a bit to it to prove the concept of adding a waterfall to his pan) I'm sure he could do a much better job and hope he will give it a go when he is less busy.
It might be nice if as well as having the platform the Imperials had a hanger for launching bombers and the like on the other side :
I have a very big version of the background image (without the bombers) if anyone else want to play about with it drop me a PM.
