Vorban            3  

Orbital             2

ThunderStone   3

I have no idea why I picked the ones I did because awarding 3 places seemed inadequate. 

There were several that should have a 1st place for different reasons.  Vorban for that background planet.  Orbital for the colors.  ThunderStone for the emotion.

Actually drawbridge's entry should be in my choices also, because of the purposeful composition and lines to draw ones eyes to the background spire. 

There are some artist that ALWAYS raise the bar for the rest of us.
