albatros: you got to work on your texturing. it looks that much thrown together that i was close to puke on my macbook :X
the overall compositing is nice but you really need to change those textures. the setting you are trying to create needs custom content. the standard valve stuff is not fitting in there. for example you take a brick wall covered with moss and grass and make a complete house side textured with it. then you have house edges cutting out of the rows and those edges dont got any detail.
you better look on other WW2 city themed maps.
