The second in a series. This is, as I hope you will recognize, Metropolis and Central City.
If anyone thinks, by the way, that I am exaggerating the Central City skyline: you're wrong. That skyline is directly copied from a Carmine Infantino-drawn Flash story.
You'll notice that I am using similar styles, colors, and effects across the series to help them tie in together. I think this will improved the effect when the entire triptych is hung.
