Excellent stuff. :3
The water trap with the half-submerged Skaven was my favorite bit of scenery. I would say your stuff is conventional for the most part, but is so well done and with such great attention to detail that it is anything but boring or common. Not only is the terrain good, but your miniatures are awesome as well - so often I see people who can do one or the other but not both at once. The Orc with the torch and the lighting is really excellent.
When I paint or model for long periods of time, I often reach a point where I feel burned out and lacking in motivation and creative energies, where I need to go in search of more until this invisible gauge is filled again. Your city has inspired me, topped off my gauge, and sated my insatiable hunger for the time being. And so, I say, the best praise I can give for your army is that viewing it was both nutritious and delicious. :3
