Ah yes, but one of the key aspects of Art Deco buildings is their size. Buildings with the look you've achieved there, are usually quite colossal, whilst the less monumental details are seen on smaller structures, like residential buildings.
I like what you've done, but as I'm strictly doing 28mm, I fear your buildings will look too small. Which is a shame, as I'm heavily involved with Pulp/Interwar settings at the moment...
