The city and texturing on the planet look great. The only advice I have is to make the atmosphere on the closest planet a little less visible on the dark side of it. And I'm not too sure if those are stars or lights on the other planet. If they are stars then they should be hidden by the planet.
But those are minor things, It still was good enough to earn a Daily Deviation !
man!! that's so awesome!! i love how the two cities look like the photos!! i'm serious that's what i actually thought you'd used!
i also lov ethe 'earth' planet (not sure if it's meant to be earth or not... he he he...) and how if you look closer you can see that a couple of the countries are literally falling apart >_<
