I love this scene; the detail of the main structure, the rocky crags in the background, and the small ships zipping around. There is a lot happening here, which creates an interesting tension against the solid unmoving feeling of ice. Faved.
I'd vote for this one! I agree, it has essences of Star Wars in it, like a hoth/coruscant mix. Love the detail on the buildings and all the shading. Keep up the good work!
