So my overall impression is that I really like where the shot is going, but for me the focal point (see attached '2019_00_BladeRunnerSand_B01 2') is competing with the composition, which is very atmospheric and moody - the spaceship doesn't enhance the composition, for me personally.
I would also consider experimenting with more color (see attached '2019_00_BladeRunnerSand_B01 3'). Again, that is just my preference, but I think there is an opportunity there to enhance the image.
