You have made a complex image strong in atmosphere, isolation, and forced perspective that helps your meaning. Only caveats: The addition of sweeter, lighter, friendlier cyans make it less a mood piece of beakness and distopia. Is that your intent? I don't think you should resit the powerful mood of isolation and despair that is possible in this image. What do you think? Cyan in lights, distant doors, and foreground wall are flattening to the image as well as disrupting mood. Sky has that color too. You may not need it. You don't have to make an appealing image, you need to make a strong image. See?
