By the way that concept art is sorta proof that the people behind TFA weren’t lying on their arses and blatantly making a reboot of A New Hope. They consciously, with EFFORT, decided to go for the look we ended up seeing. Otherwise, if you see what I mean, the concept art would be redundant.
Or they had interesting new ideas but ditched some of them for brand recognition reasons.
Maybe. But at least you can’t brand it laziness, which GL certainly can be branded with.
