It's an okay set, in my opinion. It definitely pertains to the story, but it's not a very dynamic scene in general. The selection of characters in nice, but as @Rockho said the enemy isn't very threatening. I definitely think that you should expand upon the 'concept in a box' idea more, as right now it's pretty much a rock with figures. It's not a bad set; it's just got a bit of untaped potential. Fix these issues, and it should be a lot better! I wish you good luck in the contest!
