I think that your descriptions of both the compound and Shahid were perfect. Clear enough to get us started, but not overloading us. Even some of the way he walks, and the background, adds to the mental imagery of his character. As does little things like the compound having an execution spot away from the buildings, which probably have small, blacked out windows to limit light. His ability to take out three soldiers using his camera as a weapon only adds to the idea of his physique - I picture someone strong and agile.

Perhaps they can come up in some other stories, because I would love to see more of these characters.
