Nice. At first glance looks cool, but then, oh my, some areas are really butchered :S Poor Old Town and Plac Zamkowy - I'm familiar with the area and at first was scanning trying to find it visually by the features I know are there, but then in this model it's very different (wrong color, many more floors in this model, a 20-story building where at most should be at most a 5-story, the old town castle looking like a gray residential 'blok' and not the prettier structure that it is!).

I think you're looking at something else, because the Old Town isn't on the map at all. Unless part of it failed to load for me.
