The towns in the new post are exciting!
But also a bit disappointing at the same time.
It's now clearly visible that all towns simply plop down a circular web of roads on the map and then start filling it up with buildings. All towns are perfectly circular and look all the same.
I wouldn't get disappointed just yet, as Toady is obviously still working on it. It's only when something is (at least temporarily) finalized that it's time to get disappointed. Rather, it's just time to point out the flaws or potential flaws you see, and try to give hints as to how to improve the system while he's still trying to build it up towards its final state.
It is fairly obvious when you see the one building with a grid road nearby that it doesn't look too attractive, especially compared to the major city-type that was displayed in the last update. Maybe throwing some fields down near those buildings would look better, but, as Kogut said, it would look better if the roads weren't built before there were things to connect the roads to. A single building with four roads the same size as the densely-crowded city roads crossing right at the front doorstep looks a little silly, like someone just went out and built the roads in that pattern, regardless of whether anyone lived there or not.
I don't think it would be too terrible to mark the entire region "city area", but then have portions of the landscape that is too far from the main town simply not have any roads (besides the major trade roads out of town) or buildings at all, which would help mask the notion that all cities take up the same space and are the same shape.
You could still lay out the roads, but just make them disappear until the population density that would demand expansion and the building of the road is actually present before the roads are constructed. Basically, predetermine where the road will be placed, but don't place it until there are buildings that would go alongside it.
Any outlying buildings, of course, would look much better if they had some fields to go with them, although I think that's already a given.
Also, while a brook is a step up from making a city out in some random field, you still don't build London on a creek - you build it on a natural harbor near the sea. At the very least, you build Paris far upriver on a more major river.

They put the castle and Notre Dame on an island in the middle of the river. That was a river large enough to float barges up and down the river as transport, to Le Harve (the port at the mouth of the River Seinne) if it were destined for foreign lands. (Le Harve basically just means "The Harbor".) (Technically, a little Wikisearching says Le Harve was a planned city built in the 16th century to replace the older towns of Harfleur and Honfleur, which didn't have shipyards capable of supplying the French navy any more, but the idea is still the same.)
I know we have yet to get the "large road" part in yet, and that will almost certainly help to make some roads seem larger and more important, but it still really strikes me that the "reason for the town" is now "castles" in this update.
These are all castle towns, and the towns are built radiating from the major roads leading away from the castle - the brooks that divide the town is the major obstacle on population density, and they grow up first on the side with the castle, and then closest to the bridges to the castle.
I do hope we get cities built around other purposes, or better yet, multiple purposes and job centers. I would really hope that cities with multiple purposes could morph out into different sized circles, the way Jeoshua was talking about it earlier.
A city with multiple job centers/purposes, which grows outward based upon how many jobs its job centers provide, and bounded by both the considerations of natural terrain, and where they put their city walls, would make for a much more "realistic-looking" city.
Of course, Toady hasn't said anything one way or the other, so maybe that already is his plan.
