WEll dude, sci fi is fantasy... :) Anyway, first off I would change the skies to something more spectacular.. More "rockiness" in the land masses, they're too smooth... The light in the cave is cool, the spaceship is cool... The water also needs more agitation, it's a little too plastic, foam as it brushes against the land masses... That kind of thing... Anyway, I think that would start kicking it into a direction of more lively-ness...
