It might add to the already high realism of the matte to add just a tad of haze infront of the palace to blend it in with with the background and further the illusion of depth.

It would be a useful not just as a establishing matte but if it could be extended out you could even use it to show the barge party leaving for the Dune Sea.

This is a general ESB and ROTJ thread (not a Revisted one) though it has become more ROTJ recently with people posting most of their ESB ideas on Ady's thread at the moment.

There is a lot of great stuff to look at here so it's well worth a read.
