My first pass with painting and lighting the windows and running lights. Yes, there is a faint bluish tinge to the hull. There are also subtle variations in tones throughout to make it more visual interesting without being blatant.
If you look at the underside of the saucer on the centreline toward the bow you can just make out a small green panel. That is supposed to be a hatch from which a retractable laser emitter can be deployed. That's the idea anyway. Here it's shown retracted, but if I feel like putting the effort into it I could conjure up the emitter in extended position.
