I liked the screenshots a lot.You're overlapped buildings are really good and I liked the house screenshot. You have rotated the buildings in nice ways and the size of the buildings are not to big, not too small. The paths and the natrual eyecandy isn't bad at all. Aspecialy the slave market screenshot makes your score better. However, your screenshots that are meant to be inside buildings look a little weird, and that lowers your score. I didn't like the "prison" screenshot either, actually.
Additional Comments: I'm looking forward to the scenario.
