Derive

I can't say enough what a great job you've done at creating a realistic atmosphere. The architecture is great. It should turn out to be a good infection map.

 

Really nice looking map but you way as well start dropping some of the extra scenery chunks in order to improve performance. When the Infection kicks in, you won't have time to look at pretty fittings.

You also have a few too many flickering lights all at different timing intervals. Its looks a little glitchy when its like that. Use the lens flair stuff a little more sparingly too, just because too many the same just makes a blob of annoyance in your eyes. Better to make the map overall much darker and then use lights sparingly to highlight key parts of the map.

You have really great attention to detail, just don't get too distracted that the performance becomes unplayable. Keep tweaking and testing and I am sure it will be awesome.
