Enki in Flight, i.e. "Air Taxis" (4 pieces + extras)

I could be wrong, but it seems like the "Mezi-cab" above might be a little nod to JC Mézières, who went on to do concept art for The Fifth Element, like this: (more here)

Anyway, "Enki" is Enki Bilal, previously introduced here, which includes a four-page sci-fi story.

Through the clouds, a boundless space,
Whispering wind, a gentle guide,
Earth below, where dreams reside.

Lots more pics and notes on that project here:
