Adjust the lighting!!! MeatROme is right, it looks horrible as it is now. But else... people love to complain about WQD being too high, but on modern machines, that shouldn't be a problem. Even on my machine, which isn't really the best, it runs with 13 fps while i look over the whole map in edit mode and with f5 (that's over 80.000 wqd then, http://img151.imageshack.us/img151/3558/20090709152620accitybtd.png). If i compare that my demo of Arma II, which runs at about 5fps on worst graphics settings... The problem is that you have this hanging at the beginning, due to the enormous map size. THEY SHOULD IMPROVE THE ENGINE!!! :)
For the detailing, leave it as it is. More models will make wqd even higher. I love some parts, especially things like this sofa.

I say more maps like this are needed. Give it a good lighting and maybe edit some of the textures, some extra polishing, and it's excellent.
