That is what i call a german mood!
I totaly agree, 80% Photoshop. Classic german architectural competition graphics, flavored by the all time favored switzerland "end of days" style while squinting to Zumthor feat. Dudler :-)
Nice architecture, but as usual for competitions it is not clear, if it is concrete or metal. It reminds me a little bit to this one :

Germans love slightly over composed images (yes, ich komme auch daher und kenne es kaum anders..)
But the engraved PS- inner shadow layer style of " Rettungswache Leer" is not well done, next time you should try to handle this in 3DsMax.
But I think this one will make the race!
