Well, I'm not a technoid, but to me the conversion looks pretty darn good.
For me personally, I'd do some cropping along the sides- but that's almost too subjective to even mention.
Very nice work.

Welcome to the forum ! A frozen moment in the life of your city, that nicely captures detail and (intense) activity without feeling too busy.
I notice that the brighter tones, rather than look white or close to white, look rather darker. Setting the white point (using the eyedropper in Levels or Curves) would help.
Also, but this is a matter of personal preference, you could use a little perspective adjustment to make the building wall on the left look perfectly vertical.
