What I like about this is how otherworldly it is. I've always enjoyed looking at SciFI pictures of alien cities but this one is truly alien! I also like the light effects.
But, it's gray and something that looks remarkably like the earth is right next to it. ^^
It's an awesome picture. I actually assume that's our future, forced into mega-cities, or forced off planet into space stations because of the incredible overpopulation.
Well, that's how I imagine it anyway
