Great work Hikarian (and Cromagg and Stejk, both superb Nata contestants)!.
I can tell this theme as a whole has a HUGE potential to be covered by animation.
The amount of symbolism is enourmous (and could be potentially bigger).
Probably the plan was to keep it short for this web-friendly format, but I can't help but think about a ton of additional 'symbolism' that could be added; maybe the pirate guys could've tried to persuade the man with a ton of free stuff, or another sort of monster could've appeared. Of course that's only a reflection.
Nice to see NG tank at the end :)
