That's really nice although I'm wondering if the lighting should be a bit harsher, ie the main light looks like it's coming from opposite the camera yet the far side of the ships are still well lit. That would also really make the ship interior lights pop.
I agree, the lighting isn´t good, either not setup right..or it´s just too much ambient lighting, though then again...perhaps at least the 80s movies had more of that look..they were frankly not very nice lit, so perhaps the "Bad" Lighting should be that bad
It says it should replicate miniature models, what that exactly should look like I honestly don´t know, seems to me it is either good space lighting or just cartoony lighting.
I would also suggest make some glow on the red front parts of the thruster engines as well as on the blue parts there as well.
The amount of ambient lighting to give contours and shape for the ships is often very subtle, in real sitatuatio I would say it would be pretty much complete blackness unless a planet atmosphere is under it, but that isn´t cool for movie starships so that´s why we need some slight rim and fill lighting apart from the key sun/starlight.
The rest of it is promising.
