I have a free fog plane prop on my Homepage, it's a very simple (but also very light on the processor) type of fog. Of course you can also make fog with volumetric lightning, but it takes ages to render and it's hard to get right.

And it definitely lacks shadows. I also agree with the light being of a wrong colour. At night they should be dark, blueish, not warm orange.
