Good entry Infomaniac!
I love the SNOT base and the idea is great. The little crow's nest on the mast is also nice looking. My favorite part though is the man's "shirt" on the ground.
That's a really creative idea.
A few improvements you could make are:
1) Like everyone else has said, some trans-red or plain red pieces around the man would give a nice blood effect.
2) I love the choice of head for the captain, but like Zorro said, he could use some more captain-like accessories, such as epaulettes or a bicorne with skull and crossbones, would make him look much more like a captain.
3) The first picture will be judged, so I would recommend taking one that shows the crow's nest as well, because that is a big part of your entry
Overall though, your entry is amazing! Good minifigs, exciting action and nice SNOT make this very good.
