I'm sorry that i've not been able post visual updates regularly. Right now I only have time to work on the content itself. I promise I'll post updated pictures as soon as possible. That said, I can tell you what progress I've made, which I guess will have to do for now.

I have recently completed the tavern (all stories and the basement are fully modeled and accessble) and the boat used in the aquifer. I'll post pics of them soon(tm).

I completely remodeled the inside of the park to make it feel more natural and secluded. The path to the center spirals slowly down to the central pond, now fed by a creek which comes from a wall mounted fountain. Also the only entrance is now in the front. All that stands between me and a finished park is the placement of a few more trees, uv mapping for a shrub I've added, and a few simple texture fixes. In the way of parks, the city will also have occaisional greenspaces (like road medians) filling empty spot between buildings and such. Now onto the hospital. It may seem that the hospital has been taking rather longer than any mere hospital should. The reason fir this is that when I say hospital I'm also referring to the underground aquifer and tunnels which the hospital serves as a public entrance to. The section of the aquifer which i've modeled includes floating cave algae, boats (similar to gondolas), docks and a huge central column. All I have left for this piece is to fix some seams in the aquifer texture and uv map the docks.
The slums have come a long way too. I've removed the towers that were too big, worked on the bridges between platforms, added shacks and shanties, and fenced the whole thing in. Plus I added some barrels and crates. All I have left here is to connect some parts of the fence, finish the bridges, and place the rest of the crates. Another model I've been working on is a open air amphitheatre. I need to do some more work on the seating arrangements there. As baldur and anumesa have, I too have been working on npc's. Hope to get some renders out soon.
