Some of the buildings don't look that good - and the textures aren't final, there will be some coordination effect with wall and roof tone by the end, as happened with the medieval western set...
While I like the Radcliffe Camera* as the centerpiece of #2 (as it currently is), if St Paul is in #3 then I may move the Camera to be the lower main piece in #2, which will also mean some rearranging of the factories. We will see. (if St Paul is in 3, the Camera may create a problem in the center, cause it also has a large dome).
