I've revisited the editing on this image - adding a bit of a 'glamour glow' - slight blurring to soften all of the hard lines which I hope helps to accentuate the curving metal and glass that dominate the scene. Yes, this type of effect isn't just good for portraits - use this type of blur to change the mood of most any black and white architectural image.
I find it rather ironic how man goes to such great lengths to imitate the curves so easily achieved in nature.
