and another time this great blue-orange contrast you seem to love using .
the only thing i have noticed is that the space station/mining device is fading away into the background at the upper right corner of the picture. if that is intended, you have done it pretty well. if not, then you could enhance the contrast of the space station versus the space by using reflections of the cold pale blue light [which is the colour of liquid oxygen, by the way - its not colourless. allthough that has nothing to do with your picture ] in the surface of the space station. backlight and such reflections could bring the station up a bbit against the dark background, if you want to.
