Voting time, ladies and gentlemen!
We have the usual categories:
Idea: Was it an original/creative interpretation of the theme?
Atmosphere: Was an interesting world created? - Did the scene evoke a feeling?
Design: How well the individual elements are designed, from clouds to doorknobs.
Composition: How well the elements are combined to create a pleasing whole, and lead the viewer to the points of interest.
Functionality: How well it would work as a background, with clearly defined entries and walkable areas, as well as a good viewing angle (this also includes introductionary shots of an area as long as a player character can be present in the scene).
Technique: How well it's rendered (within the chosen style!), in no way meaning the more elaborate the better.
You may elaborate on your choices, but that's optional.
I won't vote unless we have a tie.
