All of these entries were so diverse in both concept and approach. What impresses me about them all is the distinct style, all this from one program, freaky. They all have a storybook look to them, though.
What impresses me the most about Otakar's render is that he got away with putting the camera inside an interior structure. I certainly don't blame him for keeping the door open ...

I thought Volkur and Moodflow's image was a shot of the Uruk-hai marching on Helm's Deep. I thought the motion blur implied a still shot from a moving camera, but now that someone mentioned it, those could be Hurons or Ents. A really subtle render, great light.
I'm a bit anxious about Mel Brooks in LotR, that could hurt.
