1st off, the maps progression is phenomenal. You advancement from your earlier works is obvious.
That said, I am getting the distinct impression that you are centering your concerns on vista's again. Your earlier works did this. You seem overly concerned with long lines of sight. I think/feel that you should concentrate a tad bit more on your inside, short line areas more. The outside looks so good that I would (just looking at the images) say its on par with many of the big gaming title releases. However, the inside areas look as if they were added begrudgingly. I realize that that sounds a bit harsh, but as I said, I can only judge by the screens.
Look at all the screens that are less grand in distance seen. They are all bland, or nearly bland in comparison to "The Fifth Element" scenes of the outside section. The outside has architecture to spare. The inside has... boxes. The outside has colors and moving/animated scenes, the inside has boxes.
At the very least, add some color inside and many of the animated scenes, possibly via televisions or monitors. It has been my experience that movies and maps of this theme that are successful have inside areas full of advertisements with flashy bits and bobs.
I feel that this map will fall short of the expectations if all of its areas are not equally addressed. A picture may have launched a thousand ships, but many more pictures have sunk to the depths of obscurity because of short sightedness.
