Thank YOU! Your map is really gorgeous! :)
I have spent some time wandering over the map and I think it is almost impeccable and exactly what hl2dm community needs. I am pretty sure that the final version will be even more spectacular than this one :).
There are some tiny bits of the map which in my opinion might look better if you change them:
1. Those numerous cracks in the walls which are not that realistic (I am telling you this because the rest of the map, as a whole, is very realistic ) - they look quite the same, and it is difficult to understand why all the lampposts/lamps are intact while there are these major destructions...
2. There is not one quiet place in the map which is a bit wierd.
3. Although HDR is well implemented, I would consider adding darker and lighter areas so players can fully appreciate HDR effects.
It is important to keep it well lit though, as too many players complain when a map appears to be dark or has too many dark areas.
4. There is a trainstation/railroad near the area, why not try to develop it even further, getting rid of those building without windows which you use, basically, as a background.
These are just my thoughts, although I am in no position to comment on a map of this quality. Eager to see the final version!
