Very pretty ones. did you take, I mean the diagrams, from this site here included or you made by yourself??? From Sao Paulo, like the old ones, maybe you would like the Banespa tower in the old centre neighborhood part, as it has spire and let`s say a glass observation deck on it. It has some Birmann 10 I think, it is modern and has roof similar to the World Financial Centre are in NYC. From Munich the best example like the old ones that have spire and gothic impressions is the `new`Rathaus at centre.
Me personnaly prefers the Bank of China in Hong Kong as it is a composing of triangles and piramide with different roofs and also the form is spire one to the whole bldg. I think Its best example mixing old gothic concept with modern clean appearance that make it too futuristic up today and too different one.
Unfortunatly I do not know how to put diagrams like you do here, sorry, to exemplifying my descriptions.
