That fog of war looks pretty cool =D. What kind of technique you used for it? Btw, do you use mipmapping for models? Those model skins look pretty crispy there, if you don't use mipmapping, I suggest you enable it from MED (mipmapping makes the skins look softer from a distance than without mipmapping). Though models without mipmapping could be a style also, dunno how many would like it though...
