ok... i looked and i did have a save game right at the end of the episode (right before the final act) so i was able to go back to boscos and get a few shots of the wall without doing everything all over again
the first is the main shot... the second is a composite of other views of the wall gotten from clicking on other things around the wall (sorry for the huge size... figured i would just post this way so your guys could see them at full resolution, but i did compress the size a bit)
