Somehow, you managed to have a pirate-sailor adventure vibe come through clearly despite using the very urban-city-oriented sound of Dubstep. You get bonus points for that. :)
The mixing is well done, too.
Personally, I found the ending to be a little anticlimactic given the bombast of the rest of the song.
Even still, awesome job!
