Some more input.
1. Like Kolath and myself stated earlier, give the town a more damaged & battered appearance.
By this I don't just mean "wrecking" some random buildings. Make it look fought for.
Have some wrecks, possible fires, craters, rubble, dust, maybe even corpses, etc all over the city.
(Even if you keep certain areas intact, make them look more worn.)
Right now it looks like the city was just constructed
.
2. Atmosphere, get an atmosphere preset (see tutorial) that fit better.
I guess it's better than default but imho it's not a perfect match, browse through some more.
My main issues are the brightness, it makes your entire map look too clean and sunny.
3. Terrain, try to add some more elevation on the fields. If not already, your roads can use some too.
(Typical Holland phenonomon
)
4. Splats & Splines! They stick out too much.
Change the opacity of your splats & colourise your splines (look on wiki for tutorials).
This will make them blend in better and add a lot more realism.
(Non-blended splats & splines make it look artificial.)
On top of that, as always.
The more the better! (Open a Relic map for reference)
5. Sectors/Territories -
http://www.gamereplays.org/community/index.php?showtopic=1745546. Tiles. Same rule as nr 4.
Use "strenght" to change the opacity of the tiling you're using.
(Especially for grass, dirt, rubble, etc tiling)
