As you can see, this is not exactly how the originals looked. Essentially, I wanted to highlight the Tokyo Station itself and make it stand out. To achieve that I darkened everything else in the image, and then I used Topaz Labs to add detail and glow (glow through Topaz Star Effects) to enhance the building itself. That one-two punch got me most of the way there. The rest was just some digital blending and brushing to add finishing touches.
