Could I ask for critique?
I’m wondering what do you say about composition and colors of the image?
EDIT: Or if you have something else to say…?
Well, the composition is looking good, and there aren’t many colors in the scene.
I would suggest a more elaborate background, one with more colors. Perhaps an anomaly, or even another ship. Also, some color variation in the windows could go a very long way 
The modeling of the ship is superb btw
Ok, thank you, that’s interesting. Because I desaturated colors of the background. It seemed to much colorful.
Are colors of background better here (difference isn’t so expressive):
Or do you think on more dramatically change (colorful) apart of another element of attention (anomaly etc… btw it’s good tip, thanks 
)
