Lest we forget, the concept art for TFA was far more interesting than what we got, so it’s really difficult to even speculate on the look of the final result.
The TFA art is illuminating as well, because you have, for instance, let’s say five or so distinct concepts for what kind of planet Jakku might be. So even if the film did completely follow through with a cool piece of art it necessarily will not be able to satisfy every concept.
