I love the brightness and detail of the newer piece, but i also deeply appreciate the humor of the first. I find myself giggling childishly at "obey the law or we blow up your house." Quite brilliant on equal parts.
I think it's a fun concept, the idea of a city of tightropes. Everyone always likes sky cities, cities in the clouds, cities in the canyons, etc. And the perspective in the image is nice. The guy's just out for a stroll in the city, except in this city you get to walk on air.
