183000 polys - thats some size. Main thing I notice are the battlements on the centremost tower (above the main gate) are a different size to those on the other tower tops... may want to consider making them all the same size. I like the curved look of the towers above and each side of the smoother looking gateway section of the wall - to me, the side entrances to the big towers seem to match up better with the curved look of those gatehouse towers but do look a bit out of place on the very angular big towers.
