I do have other metal colours, one of my favourites is the dock style metal blue, it reminds me of my SIN mapping days. :)

The fog is certainly too thick and making everything too washed out and soft. The above screen is the new fog setting, a lot thinner but still there in the background. I certainly need to create a much higher glow from above and try to over bright the outline more.
Once I add spot lights to floor/wall areas the greyness should be pushed back. This is a night time shot with everyone gone home for the night. I am going for the central area being bright (glow from above) and the rest melting into shadows.
The crane and the various map objects (girders, machinery) are all brushwork and patches scaled up and down via ASE files. No modelling package was used, besides GTKRadiant.
Any nitpicks or thing that bugs you about the screenshot let me know. I consider all feedback.
