Spectacular, a surround mix is all that's missing. If/when you do eventually decide to revisit the picture after this iteration, there is one cut in A New Hope that I find sort of jarring that you may want to reevaluate. In the Mos Eisley approach, the portion of the shot with the Ronto rearing up that you've kept is so short that it almost plays like a mistake. I assumed its presence had to do with the timing on the soundtrack, but since you're editing a new mix anyway, I'd consider removing it entirely if I were you.
