The image is pretty cool. And there are subtle little details in there that bring you back to the OT. The stonework is in there subtly, but it looks like that could be the Massassi Temple on Yavin IV. And then there's a couple of the coats and jackets. They're very reminiscent of jackets we saw in the OT (Captain Antilles, Biggs cut scene, Luke ceremony), some of which were based on 1970's motorcycle jackets. The coat that Diego Luna has on is very reminiscent of Han's coat from Hoth...but in BLUE! And the headgear worn by one of the background characters looks very similar to headgear we saw in TESB.
It's also interesting to see Mads Mikkelson added to the cast. That guy seems like he was born to play a villain! And I could totally see him play an Imperial after having seen him in Casino Royale.
