Nice. I´d add some more detail to the white lights, add some sort of structure underneath it. Add something for the eye to focus on, right theres no real focal point in the scene. Otherwise, very cool.
This look great!! Only thing I would do is add a few more cuts to the wall modules to round them out a little more. I can see some of your poly edges in there a little bit. If you did that, I think this image would look straight out of a movie. Looks freakin' awesome!! Great job! :)
The floor is a little bit too reflective I'd say and honestly I think people are nitpicking about the shadows being too dark, it's clear that they are brighter than before. I don't think it makes a lot of sense having pipes on both sides of the walkway, mainly because it feels like it would hinder any doors coming along.…
