Quote from FrittzA lot of work has gone into making this map a little less blocky thanmost COD4 maps out there...
It's still pretty overtly blocky though. Nothing wrong with straight lines but for the location and the setting it is too blocky.
The overview shows perfectly aligned walls and houses; how about rotating some of those houses, make the walls and fences follow non-straight paths (make them broken down in places to prevent a long horizontal line).
There doesn't seem to be enough grime and dirt on the houses exteriors either. Streaks of dirt or flaking paint would add alot to the ambience.
I also think the "edges" of the map are very bland. It makes for an incredibly obvious ending; I would fill these with vegetation if you are not going to have a detailed "skybox", because currently it feels incomplete.
The lighting is also tonally very much down the middle; it doesn't sway into contrasted areas. I don't know how to fix that as I am not particularly good at lighting, but perhaps check out some other CoD4 maps to see their lighting (although if I rememebr most of their lighting is quite even, rather than dramatic).
Anyway, keep at it.
