Thanks for the reply!
Looking back over the pictures I've begun to realise that it's very difficult to see any of the detail at the distance the screenshots are taken from, what with the bloom from the rain and the height of the fog, so I'll take some more "in-game" shots during the sunrise to show off. Besides that, I'll work on more detail in the city itself where there is less.
And as for destruction, I have to agree with you. Playing over the map with friends, we've sussed that there are fewer than four undamaged buildings (all in strategically unimportant locations), whereas every other building is at half health or lower. Take it from me, artillery down the main street is devastating. But personally I'd like to add more ruins, craters and decrease the health of the buildings somewhat, so I'll work on that and post some more pictures.
